Summary on Grant Application Form
The overall aim of the proposed work is to achieve a better understanding of spontaneous interfacial convection. The way proposed to attain this is by performing experiments with selected liquid-liquid systems in 1-g and under microgravity so that comparisons can be made between results obtained in 1g, when gravitational convection may also be present, and under microgravity, when pure Marangoni convection can be observed. The experiments will involve visual observations and determination of mass transfer rates as a measure of the interfacial convection present in the systems. Interfacial conditionswill be changed by the addition of surfactants and by imposing a temperature field.Analysis of the results obtained will lead to the improvement of stability criteria for liquid-liquid systems. The need for an extension of the present mass transfer theories to include interfacial convection should also be established.
