Abstract

Convection heat transfer of power-law fluids past a wedge embedded in a porous medium Y. J. Kim School of Mechanical Engineering, Sungkyunkwan University, Korea. Abstract The problem of non-Darcy boundary layer flow past a wedge embedded in power-law non-Newtonian fluids saturated porous media is investigated. The relevant governing equations are converted to a system of first-order ordinary differential equations by means of a similarity transformation. These equations have been solved numerically, for a number of parameter combinations of wedge angle parameter m, power-law index of the non-Newtonian fluids n, first- and second-order resistance parameters, using the fourth-order Runge-Kutta integration scheme with the shooting method. Velocity, shear stress and heat transfer rate at the body surface are presented for a range of the above parameters. These results are also compared with the corresponding flow problems for a Newtonian fluid. Numerical results show that for the case
