THE INFLUENCE OF GAS DIFFUSION ON THE DYNAMICS OF A SPHERICAL LAYER OF VISCOUS INCOMPRESSIBLE LIQUID AND HEAT AND MASS TRANSFER IN IT

摘要

The formation of spherical microballoons in the case of short-term weightlessness is investigated numerically. The algorithm of the numerical solution of the problem is described and the results of numerical studies of the formation of liquid glass microballoons, saturated with carbon dioxide, are presented. The results of calculations for the problem in the full statement (mathematical model includes the influence of inertial, thermal and diffusive factors) and simplified statement, when the process of gas diffusion is not taken into account, are compared.
