Abstract


A steady-state two-dimensional flow structure in a thin liquid layer on a horizontal plate induced by a heat wave is analyzed theoretically. A long-wave approximation is used to describe the film deformation. For given temperature fields at the free surface, the distributions of flow parameters are calculated. The input of various physical mechanisms is analyzed. It is demonstrated that the motion of the local heat source can prevent the thermocapillary film rupture. A new scheme for experimental studies concerning phenomena in a non-isothermal liquid film flow is suggested.
