摘要：

The transient motion of a gas bubble induced by thermocapillary action in a low gravity environment is numerically investigated at low to moderate Marangoni numbers for the special case of high Prandtl number fluids. It was found that for Marangoni numbers greater than unity, the distance traveled by the bubble is a better scale to predict the approach to steady-state velocities than is the scaling factor R2/alpha.
