Abstract
In this present work, the unsteady radiative and MHD free convective two immiscible fluid flows through a horizontal channel have been investigated, the upper channel is assumed to be porous while the lower is non-porous. The partial differential equations governing the fluid flow are transformed to ordinary differential form by a regular perturbation method and the analytical solution for each fluid are obtained and the solution matches at the interface. The result are presented for various values of the fluid parameters such as, Grash of number, radiative parameter, and frequency parameter, Prandtl number, viscosity and conductivity ratio, It is found among others results that as the thermal radiation from wall temperature decreases, the temperature profile and thermal boundary layers increases.
