微重力下两同轴液柱内的热毛细对流的渐近解及数值模拟

摘要

A mathematical model describing the thermocapillary convection in two immisciblecoakial liquid co1umns is proposed. An approximate analytical solution is obtained byasymptotical way. The results of numerical simulation show that effective reduction of ther-mocapillary convection in the inner liquid layer can be reached by properly selecting theencapsulation which has a reasonable match relation with the encapsulated fluid.
