A survey of researchers and of manufacturers of spraying, drying, and spray heat transfer equipment was conducted. Those that responded provided descriptions of processes and devices that need developmental attention. Several of these problems are described here (eg, a unifying theory of how atomization takes place; a method of evaluating the performance of a spray used to dissolve air in water to enhance mass transfer processes; a comprehensive model for predicting heat transfer from high pressure sprays; etc). It is concluded that many research topics can be gleaned from industry as needs de

Fuel spray and atomization characteristics play a vital role in the performance of internal combustion engines. Petroleum fuels are expected to be depleted within a few decades, finding alternative fuels that are economically viable to replace the petroleum fuel has attracted much research attention. In this work spray characteristics such as spray tip penetration, spray cone angle and spray area were investigated for Karanja oil methyl ester (KOME), Jatropha oil methyl ester (JOME) and diesel fuel. The KOME and JOME sprays were characterized and compared with diesel sprays at different inject

Optical methods, imaging and non-imaging can be used in laboratory and engine tests. Imaging methods include flash photography and holography. Their use is limited to testing droplet dimensions larger than 5 µm. Imaging methods have an advantage over non-imaging ones because they allow the droplet to be seen at the point and time where its measurement is required.

However, conventional nasal fentanyl solutions can be associated with variable, and sometimes supratherapeutic maximum plasma concentrations (Cmax). To optimise rapid absorption and delivery, three novel nasal spray formulations have been developed: fentanyl pectin nasal spray (FPNS), fentanyl chitosan nasal spray (FChNS), and fentanyl in chitosan-poloxamer 188 solute (FChP).

Furthermore, increasing the Pin can increase the spray tip penetration. However, the effect of Pin on the spray cone angle was not evident.

Reducing the temperature is one of the key technologies in the metro fire emergency rescue, so it is the basic work to be done. Rapid and effective cooling can reduce the casualties caused by the metro fire. Water spray can quickly absorb a lot of heat for its large surface area. Water spray can quickly cool down the temperature of the metro fire and reduce the casualties caused by high temperature. Mobile water spray device is used in emergency rescue of the metro fire in this paper. Research on the mobile water spray device can do contribution to reduce casualties caused by metro fire.

Diesel engines are high compression ignition engine which are now very vastly used for heavy vehicles and machineries. Diesel fuel is compressed under the right condition to ignite inside the constant volume chamber. Researchers have been studying for many years on ways to increase the efficiency of diesel engine as well as reduce the emission. The main idea of this research is to understand the effect of temperature on the spray characteristics, as well as fuel-air mixing characteristics. These are the characteristics responsible for ignition of diesel sprays. This research is first conducted

As a result of the decreasing availability of authorized plant protection products, adequate pest control becomes more difficult in many ornamental crops and almost no information is available about the optimization of spray application techniques in ornamental crops. Yet, spray boom systems—instead of the still predominantly used spray guns—might improve crop protection management in greenhouses considerably. Application rate, nozzle type, and configuration will influence the spray deposition and, as such, its efficiency. In this study, spray deposition in ivy pot plants [Hedera algeriensis c

Introduction. Nasal administration is the optimal way to administer the drug to achieve maximum bioavailability in the topical treatment of nasal and paranasal sinus diseases. Due to the ease of administration and the possibility of dosing, nasal sprays have become the preferred way of active pharmaceutical substances delivery. In this regard, the composition and technology of a new nasal spray for the allergic rhinitis treatment based on fexofenadine hydrochloride and glycyrrhizic acid derivative was developed. Aim.

In this study, the 300 µm width micro-channel was manufactured by spray etching method. The surface roughness was analyzed by Laser scanning con-focal microscope. The relationship of the surface roughness and etching factor such as spray etching pressure, mask gap and time had been studied. The results show that the surface roughness increases initially, and then reduces with the size of mask gap. While the roughness increases as the spraying pressure increases. The etching time plays slightly effect on roughness for it has no impact on the etch uniformity as mask gap and spray pressure do.

Although research has shown that the COVID-19 disease is most likely caused by airborne transmission of the SARS-CoV-2 virus, disinfection of potentially contaminated surfaces is also recommended to limit the spread of the disease. Use of electrostatic sprayers (ESS) and foggers to rapidly apply disinfectants over large areas or to complex surfaces has emerged with the COVID-19 pandemic. ESSs are designed to impart an electrostatic charge to the spray droplets with the goal of increasing deposition of the droplets onto surfaces, thereby promoting more efficient use of the disinfectant.

Abstract To obtain spray resistance directly, a prismatic planing hull test was conducted in a towing tank in static water. The characteristic angles of the standing line and leading edge line of the spray zone were obtained through the fixed flight test of the whole prismatic planing hull. The prismatic planing hull was divided into front and rear parts along the standing line, and then the fixed flight state test of the split planing hull was carried out, and the spray resistance was directly measured by the front planing hull. The results show that the percentage of splash resistance in the

Spray painting robots equipped with air spray guns have been widely used in the painting industry. In view of the low efficiency of single-nozzle air spray guns when spraying large targets, a new double-nozzle air spray gun structure was designed in this paper based on the Coanda effect of double jets. Firstly, a 3-D physical model of the double-nozzle air spray gun was built in Solidworks, in which unstructured grids were generated for the computational domain by ICEM. Secondly, the spray painting process was numerically modeled with the help of the computational fluid dynamics (CFD) software

Characteristics of high-pressure liquid ammonia injection is lack of research. Spray behaviors are likely to change when a high-pressure diesel injector uses liquid ammonia as its fuel. This study uses high-speed imaging with a DBI method to investigate the liquid penetration, width, and spray tip velocity of high-pressure liquid ammonia injection up to 100 MPa.
