In the present work an experimental investigation of a drop impact onto a liquid layer of certain thickness placed on a heated thin foil is presented. The heat transfer and dynamics of drop impact on liquid surface has been studied and visualised with using infrared thermography. The experimental data obtained by means of an infrared scanner, that is, the measured temperature distributions on the opposite side of the foil will be used for the next stage of the research. The primary task of the research is to determine the heat flux from the foil by solving Cauchy problem for the non-stationary heat transfer equation that describes the heat conductivity inside the foil.

In this present paper an experimental study of a dry patch formation of the water layer on the sapphire plate is presented. With help of IR-camera the heat transfer processes are studied and visualised in water liquid layer. These results will be used for the heat transfer solution inside sapphire plate. The first of this research is to determine the temperature distribution on the upper part of sapphire glass to solve heat transfer equation for full sapphire glass.
