MIXED CONVECTION-RADIATION INTERACTION HEAT-TRANSFER IN BOUNDARY-LAYER OVER A SEMIINFINITE FLAT-PLATE EMBEDDED IN POROUS-MEDIUM WITH A TRANSFER MAGNETIC-FIELD

The convection-radiation interaction heat transfer in boundary-layer f lows over a semi-infinite flat plate in porous medium in the presence of a magnetic field is studied analytically. The conservation equation s that govern the problem are reduced to a system of nonlinear ordinar y differential equations; these are solved numerically using the metho d of superposition for small values of zeta(x), the dimensionless firs t-order flow resistance due to the presence of the solid matrix. The i nfluence of the various parameters entering into the problem on the ve locity and heat transfer are studied.
