In the present work infrared thermography is used to analyze the cooling effect of a hot solid surface induced by liquid droplets.

Abstract
In the present work infrared thermography is used to analyze the cooling effect of a hot solid surface induced by liquid droplets. In particular water droplets are released onto a BaF2 disk heated by radiation from above; the interface temperature is measured from below by means of an AVIO TVS500 infrared camera, carrying a micro-bolometric FPA sensor which operates in the long wave spectral range. The study is focused on the non-intrusive technique used to measure the transient temperature at the interface between impinging droplets and hot surface; experimental data are reported and compared with theoretical results.
