HEAT TRANSFER IN BOUNDARY LAYER FLOWPAST A CURVED SURFACE IN A SATURATED POROUS MEDIUM WITH VARIABLE PERMEABILITY
ABSTRACT
This paper is focused on the steady heat transfer in boundary layer flow past a curved surface in a saturated porous medium with variable permeability. The nonlinear coupled differential equations governing the boundary layer flow, heat transfer, and mass transfer are solved by using the two-term perturbation method with Eckert and Prandtl numbers. The similarity solutions obtained for both the zeroth-order and the first-order thermal boundary layer equations have been presented for two cases; namely, uniform permeability and variable permeability. Numerical results for the velocity and temperature profiles as well as for the skin fraction coefficient and wall heat transfer rate are obtained and reported graphically for various conditions to show the interesting aspects of the solution.
