Heat transfer at a single drop impingement on liquid–vapor–solid triple contact line

Abstract

In the current study an experimental investigation of heat transfer at a single drop impingement on liquid-vapor-solid contact line of a liquid layer located on a heated substrate has been performed. The heated thin foil technique is used for experimentation. The interaction dynamics of a drop with a contact line is considered with the help of high-speed visualization and infrared thermography. The obtained experimental data will be processed by solving inversed Cauchy problem for the non-stationary heat transfer equation. The effects of the drop impingement height on the heat flux in the region of the contact line will be determined in the further steps of research.
