Streszczenie:
Hypertonic aerosol- and dry airflow-induced bronchoconstriction were examined in the canine lung periphery by the use of a wedged bronchoscope technique. Collateral resistance was measured in anesthetized dogs before and after exposure to isotonic and hypertonic aerosols and dry airflow. Hypertonic aerosols produced significantly greater responses than isotonic aerosols, and resistance increased in an exposure-dependent manner. Atropine attenuated responses to these challenges, indicating that aerosol-induced peripheral lung constriction was, in part, muscarinic in origin. Paired hypertonic- and dry airflow-induced constriction exhibited marked differences in magnitude and time course: responses to hypertonic aerosol peaked immediately; dry air-induced responses rose slowly to a maximum 5-min postchallenge. These differences may reflect differences in stimulus strength or differences in the regulatory pathways activated by each challenge. Despite this, a significant correlation exists between aerosol- and dry air-induced responses in the canine lung periphery and suggests that changes in airway fluid osmolality have an important role in the initiation of airflow-induced bronchoconstriction.

Streszczenie:
With access to modern building technologies and HVAC-systems, it is possible to obtain low energy use and good thermal comfort for complex design, such as large building volumes. However, the situation is different for large single zone buildings with large volumes. They often have insufficient thermal comfort. The problem could be partially attributed to the unwanted airflows due to the cold surfaces, especially the windows. With increased knowledge of the airflow, it is possible to identify suitable renovation strategies in such buildings. In this work, we study a church building with mechanical air change system and floor heating. CFD-simulations with dynamic airflow was conducted based on building geometries and technical data. The validation was based on data from the ventilation control and the space-heating system. The results show how the window-to-wall ratios and the positions of windows affect the thermal comfort. It contributes with knowledge of advantages and disadvantages of different envelope design in the existing environment with floor heating.

Streszczenie:
Ceiling fans have been widely used as effective cooling and air mixing method for building environment conditioning. Understanding its airflow characteristics can be helpful to utilize ceiling fan or integrate it with background air conditioning system. However, the airflow induced by ceiling fan has different flow patterns under different rotating speeds and blowing directions. To date, it is still challenging to capture those complicated airflow fields in room scale. In this study, the airflow pattern induced by a ceiling fan was measured with a new technology, quad-view colour sequence particle streak velocimetry. A series of isothermal experiments were conducted under five rotation speed levels with downward and upward blowing directions in a room-size (4 m × 2.5 m × 3 m) chamber. Based on comprehensive three-dimensional three-component vector measurement results, the average velocity, turbulence intensity and vorticity on the middle section were calculated and used to analyse airflow patterns induced by ceiling fan. The results show that the blowing direction of the fan determines the indoor airflow pattern. When blowing downward, the flow will cause high diversion between jet core under the fan blades and surrounding region. While for upward blowing, the air speed in lower part of the room is much lower but pretty uniform. The detailed measured airflow fields can serve as reference for ceiling fan design and operation.

Streszczenie:
Sliding discharge, as a new type of electrical discharge, is being gradually applied in plasma active flow control in recent years. In this work, the particle image velocimetry (PIV) experiments were conducted to investigate the airflow characteristics induced by the sliding discharge plasma actuator at varied voltage signals. The results show that the integral thrust produced by the negative alternating current (AC) power is stronger than normal AC power under the same voltage magnitude. The induced airflow direction changes along with the changing of two power voltage signals. Furthermore, the angle of the induced airflow is mainly linear with the loading voltage.

Streszczenie:
This article concerns airflow-based odometry for estimating MAV flight speed from airflow measurements provided by a set of thermal anemometers. Our approach relies on a Gated Recurrent Unit (GRU) based deep learning approach to extract deep features from noisy and turbulent measurement signals of triaxial thermal anemometers, in order to establish the underlying mapping between the airflow measurement and the flight speed. The proposed solution is validated on a multi-rotor MAV. The results show that the GRU-based model can effectively extract noise features and perform denoising, and compensate for induced velocity effects along the propellers’ rotation axis. As a consequence, robust prediction of the flight speed is performed, including during takeoff and landing that induce ground effects and strong variations of vertical airflow.

Streszczenie:
Cable-stayed bridges are an efficient and elegant solution to bridging long spans. Though a widely used structural system, several significant issues are still unresolved regarding a cable-stayed bridge's performance, particularly with respect to the response of the cables to wind. As tension members, stay cables have a very low diameter-to-span ratio such that the effect of bending stiffness on a cable's vibration characteristics is inconsequential. Coupled with this, stay cables have very little internal mechanical damping, thus they are quite susceptible to dynamic excitation. Several vibration mechanisms have been identified, however for some, including the potentially more damaging mechanisms, the required conditions and generating mechanisms are not completely understood. Aerodynamically, a stay cable is simply a circular cylinder exposed to wind. A circular cylinder positioned normal to airflow is a touchstone topic in the fields of aerodynamics and fluid mechanics. A circular cylinder inclined to airflow, from a fundamental viewpoint, has been given very little attention considering the body of work concerning the former case. The objective of this study was to determine the characteristics of the airflow about an inclined circular cylinder, and to determine and clarify necessary conditions for the generation of galloping vibrations and high-speed vortex vibrations in dry, inclined stay cables. A wind tunnel study was conducted in which a static circular cylinder was exposed, at varying relative wind-cylinder angles, to wind speeds corresponding to a Reynolds number range of 1 x 105 to 6 x 105 Surface pressure data was recorded to determine both the instantaneous and time-averaged pressures and forces on the section. Using the matrix computation software Matlab, programs were written to evaluate and analyse lift and drag forces, and pressure, lift, and drag coefficients. From the extensive data compiled, several significant conclusions concerning flow about an inclined or yawed cylinder and about the galloping and high-speed vortex vibration phenomena result. Concerning flow about an inclined circular cylinder, the drag force coefficient is generally lower for lower relative inclination angles. This trend reverses over a small range of speeds within the critical Reynolds number range. Note that this and the following findings are based on the minimum inclination angle tested of 54.7°.

L'une des principales sources de pollution dans les environnements intérieurs est la remise en suspension de particules générées par la marche humaine. L’objectif de cette thèse est d’étudier numériquement la remise en suspension générée par la rotation d’une chaussure pendant la marche. La première partie de cette thèse présente une étude bibliographique des connaissances de la pollution particulaire. Les différentes études numériques et expérimentales sur la remise en suspension générée par la marche humaine sont recensées. Nous terminons la première partie par une présentation des différents modèles théoriques pour modéliser l’écoulement au-dessous d’un pied. Dans la deuxième partie nous exposons et nous analysons les différents modèles de remise en suspension des particules provenant d’une surface. Dans la troisième partie, l'écoulement d'air généré par la rotation d’une chaussure a été étudié numériquement à l'aide du logiciel ANSYS CFX. La méthode des frontières immergées a été utilisée pour incorporer la chaussure dans un domaine de calcul tridimensionnel. Une étude préliminaire avec une plaque large a été réalisée afin de choisir les meilleurs paramètres pour nos simulations (maillage, modèle de turbulence et test de convergence). Le modèle de turbulence k-ω SST a été choisi pour simuler le champ d'écoulement d'air instationnaire autour et sous la chaussure. Les effets de la vitesse et le type de marche, la taille de la chaussure et le motif des rainures de la semelle (rainures transversales, rainures longitudinales et absence de rainures) ont été étudiés. Les simulations numériques ont montré que pendant la rotation de la chaussure l'air sous la chaussure est éjecté sous forme de jet de parois. Après que la chaussure touche le sol, des tourbillons contrarotatifs se sont formés autour de la chaussure. Ces structures translatent horizontalement et s’éloignent progressivement de la chaussure. Dans la dernière partie, les fractions de particules remises en suspension ont été estimées à l'aide du modèle Rock 'n'Roll. En plus des paramètres étudiés dans la partie précédente, trois différentes combinaisons particules-substrat (ATD-linoléum, PSL-linoléum et alumine-acier) ont été testées. Les résultats du présent travail ont été comparés avec des travaux expérimentaux antérieurs, et un bon accord a été trouvé. Les résultats montrent que pour les différents cas étudiés, la fraction de remise en suspension varie sur six ordres de grandeur, de 10-5 à 10. Les fractions de remise en suspension des particules augmentent avec la taille des particules et la vitesse de marche. Le type de marche peut influencer la fraction remise en suspension de plusieurs ordres de grandeur. De plus, la fraction de remise en suspension diminue en réduisant la taille de la chaussure. Cependant, aucune influence significative des motifs des rainures des chaussures n'a été observée
One of the main sources of pollution in indoor environments is the resuspension of particles generated by human walking. The objective of this thesis is to study numerically the resuspension generated by the rotation of a shoe. The first part of this thesis presents a literature review of particle pollution knowledge. The different numerical and experimental studies on resuspension generated by human walking are listed. We conclude the first part with a presentation of the different theoretical models to model the flow under a foot. In the second part we present and analyze the different models of resuspension of particles from a surface. In the third part, the airflow generated by the rotation of a shoe was studied numerically using the ANSYS CFX software. The immersed solid method was used to incorporate the shoe into a three-dimensional computational domain. A preliminary study with a large plate was carried out in order to choose the best parameters for our simulations (mesh, turbulence model and convergence test). The k-ω SST model was chosen to simulate the unsteady airflow field around and under the shoe. The effects of walking speed, type of walking, shoe size and shoe groove pattern (transverse grooves, longitudinal grooves and no grooves) were studied. Numerical simulations showed that the air under the foot was ejected as a wall jet. After the shoe touches the ground, counter-rotating vortices were formed around the shoe. In the last part, the particle resuspension fraction was studied using the Rock 'n' Roll model. In addition to the parameters studied in the previous section, three different particle-substrate combinations (ATD-linoleum, PSL-linoleum and alumina-steel) were tested. The particle resuspension results were compared with previous experimental work, and good agreement was found. The results show that for the different cases studied, the resuspension fraction varies over six orders of magnitude, from 10-5 to 10. The particle resuspension fractions increase with the particle size and the walking speed. The type of walking can influence the resuspension fraction by several orders of magnitude. In addition, the resuspension fraction decreases with decreasing shoe size. However, no significant influence of shoe groove patterns was observed

This study intends to explore how to introduce the airflow lamina into the nano-gold catalyst used in gas mask filter material, and develop for removing carbon monoxide with commercialization gas mask. By applying airflow lamina into nano-gold catalysts which is made from homemade gold chloride acid and optimized preparation procedure, one can obtain not only low-cost, better catalytic activity, but also soft and strong tensile material for gas mask. Moreover, the material will also be water-vapor-resisted during carbon monoxide removing reaction, and have a portable and easy collection for commercial competitiveness. Finally, how would airflow lamina improve the flow pattern of the toxic gases in the gas mask and reduce the catalysts used amount would be discussed also. The results show that the nano-gold catalysts made by homemade chloroauric acid would be able to 100% convert carbon monoxide to carbon dioxide for 50 minutes within reaction condition of 25℃, 110ml/min air flow rate and 1vol% CO in inlet gas. Meanwhile, with using homemade chloroauric acid, the cost of the nano-gold catalysts is only about one fifth of the one using commercial chloroauric acid. A optimized preparation procedure for nano-gold/titania catalysts by homemade chloroauric acid was developed and presented in this study. For the manufacturing nano-gold catalyst supporting on the titanium dioxide powder, one optimum preparation process was developed from this research, which is preparing 7.5×10-3 M gold solution with 10 g titanium dioxide powder in a 250 ml glass or PP container, operating at room temperature and filtrating with regular filter paper. One can follow this process and scale it up to obtain high catalytic activity for CO oxidation nano-gold catalyst supporting on the titanium dioxide powder. By implementing an improved structure of respirator filter, airflow is created with increasing area and time for gas to contact the filter for improved smoke and toxicity filtration effects. Moreover, the temperature of the airflow after passing through safety mask can control in qualified spec and prevent the possibility of causing burn with using the gas mask. The airflow lamina has already obtained U.S. patent.

This study is conducted to analyze the characteristic sound signals and to reveal the relationship between averaged incoming air velocity and the flow-induced sound characteristics behind an obstacle in a pipe with various Reynolds numbers. A verifiable experiment of the quantitative analysis of sound pressure signals correlated with averaged air velocity in a pipe has been conducted using an apparatus that includes an air pump in conjunction with a pipe, a microphone, and an orifice plate, among other instruments. The analysis of the results using the fast Fourier transform (FFT) and statistical regression show that the pressure fluctuation of sound spectra can be correlated to the averaged incoming air velocity of a pipe and the approach for measuring the averaged incoming air velocity using a microphone can be justified. To ensure that the sound signals be positively identified from experimental data, the Burg method with autoregressive (AR) model is performed the analysis of the measured signals to find the characteristic frequency. Overall, it is existed a good trend between the power spectral density (PSD) of the sound pressure and the Reynolds number based on the incoming air velocity can be obtained. The experimental results using the FFT show that the pressure fluctuation of sound spectra is related to the averaged incoming air velocity in the pipe from the regression analysis, which can form the relation curve. The aerodynamic data and complicated flow structures are visualized using commercial computational fluid dynamics (CFD) package FLUENT, with Unsteady Reynolds-averaged Navier-Stokes (URANS) modelling and to use a compressible pressure-based solver simulations of turbulence flow. Simulation results of URANS indicate a similar trend with the experimental results which be pointed out that sound amplitudes are proportional to the Reynolds number as shown on comparison with experimental results, it can be shown that the approach for measuring the averaged incoming air velocity using a microphone can be validated. From the CFD simulations the flow field mechanism and the sound amplitude of air through the orifice in the pipe can be revealed. It has been found that the peak amplitude of sound is located at the edge of orifice plate, i.e. the loudest sound at this position is generated by pressure fluctuations of unsteady flow. It concludes that a microphone can be used to measure the sound pressure fluctuation of downstream of the orifice and this results can be correlated to the incoming air velocity.

This chapter reviews the common sleep disorders of pregnancy. During pregnancy and postpartum, 84% of women report poor sleep at least a few nights a week. These problems are common, disruptive to daytime and nighttime activity, and may have multiple causes. This chapter covers aspects of insomnia and restless leg syndrome. It also discusses sleep apnea in pregnancy with related hormonal changes that may increase the incidence. There is an association of sleep apnea and pregnancy-induced hypertension, with increased adverse outcomes of pregnancy, including fetal growth retardation and premature birth. It has been suggested that treating nocturnal airflow limitation may improve gestational hypertension. The recommended therapies in this chapter may also be applied to non-pregnant patients with similar complaints.

This chapter describes how additional information can be obtained during an exercise test to detect the airflow obstruction of exercise-induced asthma. The forced expiratory volume in one second (FEV1) may fall a few minutes after cessation of exercise, but this test is not particularly sensitive for detecting exercise-induced bronchoconstriction. The flow–volume loop during exercise can be compared with the pre-test maximal trace to detect expiratory airflow limitation. Addition of inspiratory capacity measurements can be helpful. The flow–volume loop may also suggest exercise-induced laryngeal obstruction, which can be confirmed by continuous fibreoptic laryngoscopy during exercise.

The combustion properties of several dead Mediterranean forest fuels were investigated experimentally. Samples of straw, eucalyptus, shrubs, and Pinus Pinaster with the same load were placed in cylindrical containers of the same size and were ignited from the perimeter of the container's bottom. A pitot tube and a thermocouple are placed one meter above the fuel surface to measure the airflow induced by the flame and the flame temperature. The main combustion parameters (mass-loss rate, flame height and temperature, and the induced air velocity) seem to evolve according to the same trend regardless of the fuel type. They increase rapidly in the growth phase of the flame then they decrease over a relatively long period characterizing the decay phase. In the crossover period between these two burning phases, the flame is fully developed with a maximum height and burning rate. The time required for the burning rate to attain its maximum value seems to vary only slightly with the fuel type. The maximum flame height and burning rate are found to be the largest for shrubs and the lowest for straw. The flame temperature and airflow are found to depend on the position in the flame with maximum values near the continuous zone of the flame.

We report the research progress made in our research efforts to utilize the thermal effects induced by DBD plasma actuation to suppress dynamic ice accretion over the surface of an airfoil/wing model for aircraft icing mitigation. While the fundamental mechanism of thermal energy generation in DBD plasma discharges were introduced briefly, the significant differences in the working mechanisms of the plasma-based surface heating approach from those of conventional resistive electric heating methods were highlighted for aircraft anti−/de-icing applications. By leveraging the unique Icing Research Tunnel available at Iowa State University (i.e., ISU-IRT), a comprehensive experimental campaign was conducted to quantify the thermodynamic characteristics of a DBD plasma actuator exposed to frozen cold incoming airflow coupled with significant convective heat transfer. By embedding a DBD plasma actuator and a conventional electrical film heater on the surface of the same airfoil/wing model, a comprehensive experimental campaign was conducted to provide a side-by-side comparison between the DBD plasma-based approach and conventional resistive electrical heating method in preventing ice accretion over the airfoil surface. The experimental results clearly reveal that, with the same power consumption level, the DBD plasma actuator was found to have a noticeably better performance to suppress ice accretion over the airfoil surface, in comparison to the conventional electrical film heater. A duty-cycle modulation concept was adopted to further enhance the plasma-induced thermal effects for improved anti−/de-icing performance. The findings derived from the present study could be used to explore/optimize design paradigm for the development of novel plasma-based anti−/de-icing strategies tailored specifically for aircraft icing mitigation.

This paper presents piezoelectric energy power generator exploiting direct conversion of airflow into mechanical vibrations. The device consists of two tightly coupled parts: a mechanical resonator, which produces high-frequency mechanical oscillation from quasi-constant airflow, and piezoelectric power generator harvesting the energy from the resonator’s motion. The proposed energy harvester allows for locking up the devices lowest natural frequency to the vortex-shedding resonant frequency induced by the ambient energy source. The Energy Harvester demonstrated a peak-to-peak output voltage of 20V at 10Hz, from an input wind velocity of ∼7 m/s.

Streszczenie:
Review question / Objective: Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease characterized by persistent respiratory symptoms and progressive airflow obstruction documented on spirometry. Acupuncture, as a safe and economical non-pharmacology therapy, has pronounced therapeutic effects in COPD patients. Several systematic reviews draw the conclusion that acupuncture could improve patients’ quality of life, exercise capacity and dyspnoea, however, the results about lung function were inconclusive. Recently, increasing number of animal studies has been published to illustrate the effects of acupuncture in improving lung function in COPD animal model. However, the efficacy of acupuncture for experimentally induced COPD have not been systematically investigated yet. A systematic review of animal experiments can benefit future experimental designs, promote the conduct and report of basic researches and provide some guidance to translate the achievements of basic researches to clinical application in acupuncture for COPD. Therefore, we will conduct this systematic review and meta-analysis to evaluate effects of acupuncture on COPD animal model.
