Gravity effect on spray impact and spray cooling
Microgravity Science and Technology, 2007An experimental study of the film produced by the spray impact on a heated target and of the spray cooling has been performed in normal gravity and in microgravity conditions during parabolic flights. A convex shape of the target allowed visualization of the film evolution and determination of the film characteristics using the image processing.

Water spray cooling of polymers
Polymer Engineering & Science, 2011AbstractThe cooling process in conventional rotomolding is relatively long due to poor thermal conductivity of plastics. The lack of internal cooling is a major limitation although rapid external cooling is possible. Various internal cooling methodologies have been studied to reduce the cycle time.

Local anaesthesia for minor surgery can be produced by reducing the skin temperature, but slight reduction of the skin temperature, insufficient to cause local anaesthesia, is also said to relieve pain and muscular spasm. For many years ethyl chloride sprays have been used for this purpose.

Journal of Electronic Packaging, 2007
The popularity and increased usage of insulated gate bipolar transistors (IGBTs) in power control systems have made the problem of cooling them a subject of considerable interest in recent years. In this investigation, a heat flux of 825W∕cm2 at the die was achieved when air-water spray cooling was used to cool IGBTs at high current levels.

Symposium (International) on Combustion, 1988
A series of 25 fire tests was conducted to investigate cooling in room fires by sprinkler spray. The tests were conducted in a 3.66 m× 7.32 m×2.44 m high test room, which had a 1.22 m×2.44 m high opening centered in one of the 3.66 m walls. The fire source was a spray fire with constant heptane flow rate located opposite the room opening.

Spray cooling with ammonium hydroxide
International Journal of Heat and Mass Transfer, 2017Abstract An experimental study was conducted to investigate the performance characteristics of spray cooling with ammonium hydroxide (NH 4 OH) binary mixture for high heat flux removal. Two mixtures, having ammonia mass fractions of 0.3 and 0.5, were selected to represent practical operation conditions near atmospheric pressure and room temperature ...

High Power Density Spray Cooling
1989Abstract : The research reported describes experimental and theoretical investigations of high power density evaporative spray cooling. Preliminary experiments demonstrating heat fluxes greater than 1,000 W/sq cm were conducted. Extensive laser phase Doppler measurements for spray characteristics were also taken.

Management of surface cooling non-uniformity in spray cooling
Applied Thermal Engineering, 2020Abstract The existence of the hot spot area in the impact center of spray cooling indicates that the temperature is not uniform on a relative large spray-covered surface. In this study, the temperature distribution on a large spray-cooled surface is experimentally studied, and cooling non-uniformity ( CNU ) is defined to quantify the global and
