The structure of convective flows in a horizontal evaporating layer of liquid (ethanol) was studied experimentally depending on the velocity of gas (air) flowing near the interface. Using the PIV method, we measured distribution of the two-dimensional velocity field and visualized the convective flows in a liquid layer. The existence of a vortex flow structure in an evaporating liquid layer, when the interface moves towards the gas flow, was proved.
- thermocapillary interface
- two-phase flows
