Experimental study on Marangoni convection
Abstract
The natural convection in a rectangular container driven by surface tension gradient is investigated in the laboratory and the Marangoni effect under microgravity is estimated. The flow patterns are visualized and the velocity distributions are obtained under various thermal conditions and aspect ratios. The flow and the temperature fields of the Marangoni convection strongly depend on the coupled buoyant convection and the aspect ratio of the liquid layer. Thin wires placed on the free surface and the external magnetic field reduce the convective motion considerably and are expected to be effective means for obtaining desirable flow conditions.
