Experimental study of moving liquid layer evaporation under gas flow into rectangular minichannel

Abstract

The paper presents the experimental results on the mass evaporation rate from the moving liquid layer surface streamlined by the gas flow for different layer thicknesses. The maximum value of the mass evaporation rate was observed for a 5 mm liquid layer. Further increase in the thickness of the liquid layer causes a decrease in the mass evaporation rate. The assumption about the change in the balance of forces was made. A self-organized structure of the square-shaped spatial cells is found to form in the moving liquid layer streamlined by the gas flow. This structure has the most visible form at the maximum possible velocity of the air.
