Item The paper proposes a theoretical model for the study of flow and heat transfer in a parallel plate channel, one of whose walls is lined with non-erodible porous material, both the walls being kept at constant temperatures. The analysis uses Brinkman model in the porous medium and employs the velocity and temperature slips at the interface (the so called nominal surface). The influence of the thickness as well as the permeability of the porous medium on the flow field and Nusselt numbers at the walls is investigated. © 1983 Springer-Verlag.(Springer-Verlag, Convective heat transfer in a parallel plate channel with porous lining) Channabasappa, M.N.; Umapathy, K.G.; Nayak, I.V.1983Item The flow and heat transfer in an annulus between rotating coaxial cylinders, with non-erodible porous lining, is investigated. The flow in the porous lining is obtained by using Brinkman equation. At the boundary between the porous lining and the free flow (the so called nominal surface), the velocity slip and the temperature slip are used. A quasi-numerical technique developed by the authors is employed in obtaining the solution of the energy equation. The effect of the thickness of the porous lining and the permeability on the velocity and the Nusselt numbers at the walls is studied. © 1986 Springer-Verlag.(Springer-Verlag, Heat transfer by rotational flow in an annulus with porous lining) Channabasappa, M.N.; Umapathy, K.G.1986
