THERMO-DIFFUSION AND DIFFUSION-THERMO EFFECTS ON FREE CONVECTION FLOW PAST A HORIZONTAL CIRCULAR CYLINDER IN A NON-DARCY POROUS MEDIUM
RÉSUMÉ
An analysis is presented for the steady free convection heat and mass transfer past a horizontal circular cylinder plate in a non-Darcy porous medium with Soret (thermo-diffusion) and Dufour (diffusion-thermo) effects included. The non-Darcy effects are simulated via a second-order Forchheimer drag force term in the momentum boundary-layer equation. A parametric study illustrating the influence of Darcy parameter Da, Forchheimer parameter Λ, Grashof number Gr, Schmidt number Sc, Soret number Sr, Dufour number Du, transpiration parameter fw, on the fluid velocity, temperature, and concentration profiles, as well as local skin friction, Nusselt, and Sherwood numbers, is conducted. Increasing Darcy number accelerates the flow due to a corresponding rise in permeability of the regime and concomitant decrease in Darcian impedance. Applications of the model arise in metallurgical materials processing, chemical engineering, flow control, etc.
