Thermographic investigation of surface temperature of the evaporating liquid layer under the action of gas flow

Abstract

An experimental study of the temperature field on the surface of horizontal liquid layer (Ethanol) evaporating into gas flow (Air) has been performed. Temperature gradient of the gas-liquid interface has been measured with the help of Titanium 570M IR camera. Shear stresses on gas-liquid interface induced by thermocapillary effect and inert gas flow have been defined.
