The study of marangoni convection around vapor bubble under microgravity

摘要

Transient Marangoni convection under micro and earth gravity conditions around a vapour bubble submerging in superheated liquid-filled rectangular container is simulated with a two dimensional model. A finite difference technique is employed tonumerically integrate the unsteady voticity and heat transport equations. Through simulating the distribution of stream function and temperature, steady state Nusselt Number at the top and bottom walls as a function of Marangoni Number, the response of the maximum stream function and heat transfer to increasing temperature difference of top and bottom walls were obtained.
