Résumé

Spray cooling of a hot surface was investigated in the second of two papers to determine the effect of mass flux, Weber number, and degree of subcooling on two different working fluids such as pure water and R134a. Full cone circular sprays were used to cool a circular surface of diameter 80 mm with an initial temperature about 250/70 °C for pure water/R134a, respectively. Both the transient liquid crystal technique (only for R134a) and thermocouple wire temperature measurements were conducted. Cooling curves were obtained in a wide range of the above-mentioned parameters. (See also this Bulletin, reference 2005-0630.)
