Dissipative Effect on Heat and Mass Transfer by Natural Convection over a Radiating Needle in a Porous Medium

摘要

The paper deals with the effects of buoyancy (N), Lewis number (Le), radiation parameter (R), and viscous dissipation (Ec) on the natural convective heat and mass transfer from a radiating needle in a porous medium. In the analysis of the problem, an integral approach of Von Karman type has been adopted, and the numerical values computed pertaining to the local Nusselt and local Sherwood numbers have been compared with the earlier published values. The results have been found in excellent agreement.
