Convection flow study within a horizontal fluid layer under the action of gas flow

Abstract

Abstract. Experimental investigation of convective processes within horizontal evaporating liquid layer under shear-stress of gas flow is presented. It is found the structures of the convection, which move in opposite direction relative to each other. First convective structure moves in reverse direction with the flow of gas, and the second convective structure moves towards the gas flow. Convection flow within the liquid layer is registered with help of PIV technique. Average evaporation flow rate of Ethanol liquid layer under Air gas flow is measured. Influence of the gas velocity, at a constant temperature of 20 0 C, on the evaporation flow rate has been studied.
