Abstract:

The thermodynamic effect on cryogenic cavitating flow characteristics of pressurized liquid nitrogen in a horizontal rectangular nozzle is precisely investigated by numerical analysis based on an unsteady thermal nonequilibrium two-fluid model and by flow visualization measurement. According to the numerical and experimental study, the sufficiently useful results are proposed to realize the further development and high performance of a type of cryogenic two-phase cooling system. It is numerically and experimentally found that the inception of cryogenic cavitation occurs and the cavity grows in

Abstract:

Hydraulic cavitation is usually an undesirable phenomenon since it can damage the concrete surface of a chute spillway. In order to numerically predict the potential cavitation of a high-speed flow in a chute spillway, a compound risk assessment is proposed by combining probabilistic analysis with a computational fluid dynamics (CFD) technique. Based on the local pressure and flow velocity of the nodes, the traditional cavitation number is introduced to characterize the possibility of cavitation. The distribution of cavitation numbers was obtained according to the numerical simulation of the f

Abstract:

The theory of stress-induced cavitation is applied here to the problem of cavitation of a viscous liquid in the streaming flow past a stationary sphere. This theory is a revision of the pressure theory which states that a flowing liquid will cavitate when and where the pressure drops below a cavitation threshold, or breaking strength, of the liquid. In the theory of stress-induced cavitation the liquid will cavitate when and where the maximum tensile stress exceeds the breaking strength of the liquid. For example, liquids at atmospheric pressure which cannot withstand tension will cavitate whe

Abstract:

The flow in a Francis turbine at full load is characterised by the development of an axial vortex rope in the draft tube. The vortex rope often promotes cavitation if the turbine is operated at a sufficiently low Thoma number. Furthermore, the vortex rope can evolve from a stable to an unstable behaviour. For CFD, such a flow is a challenge since it requires solving an unsteady cavitating flow including rotor/stator interfaces. Usually, the numerical investigations focus on the cavitation model or the turbulence model. In the present works, attention is paid to the strategy used for the time i

Abstract:

AbstractThe acoustic cavitation phenomenon constitutes a potential hazard in ultrasound diagnostics and therapy so that early and effective detection of cavitation is of great interest. However, cavitation might even bring a higher risk especially when an echocontrast agent based on microbubbles is used. The major goal of the present work was to develop a cavitation detection method based on increased level of cavitation noise in the range of low frequencies (about 1 Hz). This method was applied in vitro using a model of body fluid containing a model echocontrast agent, such as 5% solution of

Abstract:

Cavitation is an important factor on influencing the safety and efficiency of hydraulic machinery. So cavitation characteristics and mechanism are the work targets of many scholars. And how to reduce the risk of cavitation is also a hot issue. In this paper, geometry structure of hydrofoil is changing, with different number and angle of hole. Flow fields of hydrofoil are analyzed and compared, and then the effect of drilling angle on flow field of hydrofoil is given. This study introduces geometry optimization ideas for improving cavitation in the area of hydromachinery.

Abstract:

This textbook has covered the common causes of broken down teeth: dental caries, tooth wear, and trauma. In addition, long-term failure of parts, or all, of the existing tooth–restoration complex can be significant and may require further operative intervention for its successful management (see Chapter 9). Many intra-coronal defects can be repaired with direct adhesive restorations, as discussed in Chapters 5 and 9. However, the situation can be complicated by the loss of significant portions of existing restoration or tooth structure (e.g. cusps, buccal/lingual walls), which influence the restorative procedures used in an attempt to maintain the tooth longevity, as well as pulp viability, for as long as possible. For direct restorations to succeed clinically, they require healthy dental tissues to aid support, retention, and ideally provide an element of protection from excessive occlusal loads. With diminishing amounts of tooth structure to work with, greater thought and care are required to manage and prepare the remaining viable hard tissues to support and retain the larger restoration. The core restoration describes the often large direct plastic restoration used to build up the clinically broken down crown. It is retained and supported by remaining tooth structure wherever possible (sometimes including the pulp chamber and posts in root canals of endodontically treated teeth). These large restorations often benefit from further overlying protection to secure their clinical longevity, by means of indirect onlays, and partial or full coverage crowns. Before carrying out a detailed clinical examination of the individual tooth and the related oral cavity, it is always important to justify your clinical decisions, for both operative and non-operative preventive interventions. The five key reasons for minimally invasive (MI) operative intervention are:… • to repair hard tissue damage/cavitation caused by the active, progressing caries/tooth-wear process (where non-operative prevention has failed repeatedly) • to remove plaque stagnation areas within cavities/defects which will increase the risk of caries activity due to the lack of effective plaque removal by the patient • to help to manage acute pulpitic pain caused by active caries by removing the bacterial biomass and sealing the defect, thereby protecting the pulp • to restore the tooth to maintain structure and function in the dental arch • aesthetics.

Abstract:

In 1968, Drs Pravin M. Shah and Raymond Gramiak at the University of Rochester, New York, were conducting a study with the ultimate goal to investigate whether heart stroke volume could be estimated from the extent and duration of cusp separation of the aortic valve, as measured with M-mode ultrasound. Simultaneously, as the reference, they also measured cardiac output with the indicator dilution technique. Here, a bolus of a dye (indocyanine green) is injected and blood is sampled downstream to determine the rate at which the indicator has been transported from the injection site. In Dr Shah’s own account of the experiments, he explains that the routine at his university then was to place a catheter in the left atrium with the trans-septal technique, i.e. inserting the catheter in a vein and penetrating into the left atrium via the right atrium. During the injections of the dye, somewhat to their surprise, they observed a striking echo enhancement across the aorta. The enhancement also appeared when saline and dextrose in water was flushed through the catheter. Dr Gramiak reminded himself of a comment from Dr Claude Joyner, that a temporary echo-enhancement could be observed during saline injections, and they speculated that miniature bubbles produced by gaseous cavitation upon rapid injection of the fluid gave rise to the enhancement, and raised the idea that this could be used as a contrast agent. An in vitro study by Frederick Kremkau provided strong evidence that gas bubbles were actually responsible for the echo enhancement. It is interesting to note how discoveries are made independently around the world, when the time is ripe. At the same time in Lund, Drs Inge Edler and Kjell Lindström performed studies to measure blood flow in the heart. At this point no ultrasound Doppler signals had been recorded from the inside of the heart, and they used a calf heart in an in vitro model to verify that signals could be obtained when water and blood was led through the model.

Abstract:

Shortness of breath essentially means either that not enough oxygen is getting around the body or that there is a cause for increased respiratory drive. This could be due to many causes, as shown in Figure 10.1: • Timing of onset? This is crucial because vascular (e.g. PE) and mechanical (e.g. pneumothorax, foreign body) pathologies present suddenly. At the other end of the spectrum, it may take weeks or months before diseases such as lung cancer or pulmonary fibrosis cause sufficient dyspnoea for the patient to present. • Alleviating or exacerbating factors? Most shortness of breath will be worse on exertion. However, heart failure will also be worse on lying flat; asthma will usually be worse at certain times of the year (e.g. due to pollen allergy, cold climate), in certain places (e.g. in dusty environments, or when the pets are around), during intense cardiovascular exercise (e.g. running), or in the early hours of the morning. Psychogenic hyperventilation will be worse at times of anxiety and stress. • Smoking? Never forget to ask about smoking and to quantify this in terms of ‘pack years’ smoked (1 pack = 20 cigarettes; 20 cigarettes a day for a year = 1 pack year). • Pets? The patient may be allergic to pets, especially new ones. • Occupational history? Ask about jobs—there are still lots of people who have been exposed to asbestos, silica dust, and coal particulates in past jobs and who are at risk of pneumoconioses. • Medications? Certain drugs can cause hypersensitivity pneumonitis (previously called extrinsic allergic alveolitis, a type of interstitial lung disease), e.g. nitrofurantoin, amiodarone, methotrexate, bleomycin. • Past medical history? Autoimmune conditions such as rheumatoid arthritis and systemic lupus erythematosus can cause interstitial lung disease and pleural effusions. • Cough? A cough points strongly towards a respiratory pathology. The nature of the cough is important: Is it productive? What colour is the sputum? Is there any blood? When does the cough occur? What does the cough sound like? A persistent, productive cough over the last few days suggests pneumonia; a persistent, productive cough on most days of the past 3 months and spanning years suggests chronic bronchitis; a dry cough present mainly during the episodes of shortness of breath or at night suggests asthma, but may also be a feature of left ventricular failure; bloodstained sputum may suggest a PE, lung cancer, or a cavitating pneumonia.

Abstract:

The coal oil slurry valves are located between the high pressure and intermediate pressure separators in the direct coal liquefaction unit. Because of the high pressure drop between the valve inlet and outlet, the cavitation occurs immediately once the coal oil slurry enters into the valve.

In this paper, a numerical-experimental investigation on the erosion-cavitation wear of coal oil slurry valve is conducted. The cavitat

Abstract:

Implantation of a bileaflet mechanical heart valve (BMHV) continues to be associated with a risk of thromboembolic complications despite anti-coagulation therapy1. This has been attributed to the structurally rigid design of the leaflets and valve mechanics combined with an intricate hinge mechanism for the rigid leaflets. The lack of a built in compliance within the valve mechanics presumably leads to sharp stress gradients within the flow as well as a violent closure of the valve often associated with the audible impact of the leaflets to the housing, and a potential for momentary cavitation
