Surface mobility of surfactant solutions. XI Numerical analysis for the Marangoni and the gravity flow in a thin liquid layer of triangular section

Abstract

The numerical calculation method of the “simplex” finite elemente is applied to the Marangoni flow undergone by the surfactant solutions, as well as to the simultaneous gravitational flow inversely oriented and occurring in competition with the former.

The order of magnitude, for the experimental rates of flow corresponding to the two types of thin liquid layer movement is “surface canals” of angular section, is in agreement with that obtained by applying the above-mentioned method of calculation.
