Abstract

The Marangoni flow of an incompressible viscous fluid through an inclined canal having triangular section and a free liquid/gas surface is discussed. In comparison with the previously proposed models, 1-2-4-5 in the present one the existence of a surface viscosity of the liquid and the fact that the process is non-steady are taken into account.

A numerical analysis of the mathematical model is done, by using a Galerkin-Crank-Nicholson algorithm. By taking notice of the non-stationarity of the process the occurrence of the Marangoni-type flow in competition with the gravity flow is elucidated.
