A Numerical Study of Convec1tive Heat Transfer through a Porous Medium in a Vertical Channel with Radiation Effect

AbstractWe analyze the effect of Radiation on the Convective Heat Transfer flow of a viscous electrically conducting fluid in a vertical channel bounded by the flat plates at x=±1. Which are maintained at Non uniform Temperature in the presence of Heat sources taking the slope δ of the boundary temperature the Non-linear coupled equations governing the flow and Heat Transfer are solved by employing a regular perturbation technique .We notice an enhancement in the vicinity of the boundary η=±1 and depreciates marginally in the central region of the flow. In this analysis we investigate the effect of Radiation on Convective Heat Transfer flow of a Viscous Incompressible electrically conducting fluid in a Non-Uniformly vertical channel. We take the Prandtl Number P=0.71 and δ = 0.01.The Velocity components u,w and The Non-dimensional Temperature distribution θ and the rate of heat transfer has been calculated numerically for different values of the governing parameters
