Heat transfer during spray water cooling using steady experiments

TL;DRAbstract

Spray water cooling is widely used in many industrial processes to control heat removal from a hot material surface. In order to control heat transfer rates and obtain desired surface temperature distributions, a deeper understanding of fundamental spray cooling dynamics and more accurate estimation of spray heat transfer rates is needed. In this thesis, a new technique combining experiment and computational modeling has been developed for measuring the steady-state heat transfer extracted locally by water sprays or air-mists impinging on the surface of a hot metallic sample. 
\n\tThe experimental apparatus was developed by A. C. Hernandez B., H. Castillejos E, and F. A. Acosta Gat CINVESTAV, Mexico, and is designed to be able to employ spray water to cool the metallic sample accommodated inside a copper coil with an alternating current as induction heating goes on inside the sample. Control of total input power from the wall maintains each desired sample thermocouple temperature.
