Mass And Heat Transfer

In this paper we study the effect of Mass and Heat transfer under the existence of transverse magnetic field for an oscillating two dimensional Micro-polar fluid flow through a moving infinite permeable plate in a porous medium. Investigate the Solutions for angular momentum, governing momentum, energy and concentration equations. Study the effect of chemical reaction, permeability parameters, velocity profiles, micro rotation profiles, wall stress coefficient and skin friction coefficient by using graph.

The paper is devoted to a theoretical investigation of wave processes in moist porous media saturated with gas. Interfacial forces of interaction, heat exchange between the skeleton of a porous medium, liquid and gas, mass transfer between a liquid and a gas; material of the skeleton of a porous medium is considered viscoelastic, the liquid covers the inner surface of the pores of the medium with a thin uniform layer. The propagation of acoustic waves is considered in the two-velocity approximation. A common system is recorded equations and physical relationships describing the propagation of acoustic waves in a wet porous medium. A dispersion relation is obtained. Influence of heat transfer between phases on propagation ”Fast“ and ”slow“ waves is taken into account on the basis of the heat conduction equation.
