High-speed video recording and IR thermography to study the characteristics of a two-phase flow and heat transfer during spray cooling of a heated surface
The possibility is shown of measuring the temperature field, the droplets sizes, and the irrigation pattern of an impact surface during spray cooling with the use of high-speed IR thermography, video visualization, and a transparent design of the heating element. New experimental data on the heat transfer intensity are obtained. In particular, it is shown that the heat transfer coefficients during spray cooling are $1.5$ times higher than the maximal heat transfer under multijet cooling regime. The liquid flow rate for the spray nozzle is lower by almost $5$ times compared to the multijet nozzle.
