This paper deals with the problem of thermal radiation effects on magneto
hydro dynamic flow and heat transfer in a channel with porous walls of
different permeability. The equations governing the flow are coupled
non-linear partial differential equations. By introducing the stream
function, the governing partial differential equations are reduced to
ordinary differential equations. The governing equations which are coupled
and highly non-linear are first linearized by quasilinearization technique
and obtained numerical solution by using implicit finite difference scheme.
The effects of various parameters, namely, Reynolds number R, Permeability
parameter K, Hartmann number S2, Prandtl number Pr, and Thermal radiation
parameter F, entering into the problem on the velocity field and temperature
distribution are shown graphically.
