The dynamics of evaporation from the confined surface of a horizontal layer of liquid (ethanol) under the action of a gas (air) flow has been experimentally studied. The influence of the longitudinal dimension of the interface (0.01–0.03 m) on the specific mass rate of evaporation was studied. It was found that the specific mass evaporation rate decreases with an increase in the interface length due to a decrease in the vapor concentration gradient in the boundary layer.

气流作用下界面长度对水平液层蒸发速率的影响

实验研究了在气体（空气）流动的作用下，液体（乙醇）水平层的受限表面蒸发的动力学。研究了界面的纵向尺寸（0.01–0.03 m）对特定比蒸发速率的影响。发现由于边界层中蒸气浓度梯度的减小，比质量蒸发率随着界面长度的增加而减小。
