Abstract: | The interaction between gravity convection and Marangoni convection in a horizontal rectangular channel filled with a liquid
containing a surfactant and a drop of another liquid is numerically investigated. For large Schmidt numbers the occurring
oscillatory regime of solutal convection is analyzed. In the model with a surface phase the effect of the adsorption and desorption
processes on the convective flow structure is determined. The corresponding initial and boundary value problem is solved using
a difference method. |
