Abstract
The paper is devoted to the experimental study of convection in a horizontal evaporating liquid layer (ethanol) of limited size under the action of gas flow (air). The two-dimensional velocity field in the liquid layer is obtained using the PIV method. The existence of a vortex convective flow within a liquid layer directed towards the gas flow has been revealed.
Highlights
Studying heat and mass transfer through the interface between liquid and gas is one of the most important problems nowadays
Works in this area is extremely insufficient for comprehensive understanding of the physics of processes related to heat and mass transfer through the interface between liquid and gas, as well as convection in the liquid layer
The experiments were conducted at atmospheric pressure in a test section, and a stationary 3 mm thick liquid layer
Summary
Studying heat and mass transfer through the interface between liquid and gas is one of the most important problems nowadays. The convection flows within the evaporating liquid layer into inert gas, are actively studied experimentally [1,2,3,4] and theoretically [4,5,6,7] in the present time. Works in this area is extremely insufficient for comprehensive understanding of the physics of processes related to heat and mass transfer through the interface between liquid and gas, as well as convection in the liquid layer
