AbstractTwo-dimensional and unsteady problems of drop and bubble Marangoni migration are calculated for cases of larger Reynolds numbers in the microgravity environment. A global treatment method is introduced to solve numerically the complete problem by using the finite differential method, and the thermocapillary force acting on the interface is considered as a body force acting in the computational mesh elements which are passed by the interface. The program of numerical simulation is checked with the symmetric model of bubble migration in Ref. [1]. The asymmetric model of bubble migration is calculated, and the results are different fi om that of the symmetric model. The asymmetric model of drop migration is also calculated. The trajectory of drop in larger Reynolds number fluid is oscillated periodically due to the vortex separation in the wake. (C) 1998 Elsevier Science Ltd. All rights reserved.
