Combined convection of conducting binary mixture in presence of heterogeneous chemical reactions

M. Z. Zhivov - Yu. A. Sokovishin - Yu. V. Vasil'ev

The numerical solution of the problem of convective heat and mass transfer of a conducting binary mixture of gases near a vertical plate in a transverse magnetic field is examined. The boundary-layer equations are written in the noninductive approximation. The expressions for the boundary conditions and heat and mass fluxes at the wall include the Stefan flow, which is due to the occurence of heterogeneous chemical reactions involving a phase change. It is shown that the development of natural convection leads to a significant increase in the friction and heat and mass transfer at the wall. As a result, the magnetic field has different effects on the flow in different cross sections. In the initial region of flow the field intensifies transport processes but later, as natural convection develops, it has the reverse effect.
