Surface mobility of surfactant solutions XVII. Determination of Marangoni rate of flow in simulated zero gravity conditions

6 years ago

Abstract

Values of the Marangoni rates of flow experimentally determined for a thin liquid pellicle found in inclined canals have been extrapolated to zero hydrostatic level differences. Comparison of the so obtained data with the rates of flow measured on horizontal canals shows a satisfactory agreement within the experimental errors. The two experimental variants differently simulate the microgravity conditions in which only surface forces continue to operate.
