【 摘 要 】

Study of convection in a horizontal liquid layer (ethanol) evaporating into the gas flow (air) has been performed.The two-dimensional velocity field in the liquid layer is obtained using the PIVmethod. It is shown that the temperature rise induces significant changes in the convective flow structure. The main factor determining structure of convective flows within the liquid is the thermocapillary effect.
