Item The effect of the thickness of the porous material on the parallel plate channel flow when the walls are provided with non-erodible porous lining(1976) Channabasappa, M.N.; Umapathy, K.G.; Nayak, I.V.Flow through a channel whose walls are lined with non-erodible porous material is investigated using Beavers and Joseph slip boundary condition. It is shown that the effect of porous lining is to increase the mass flow rate and to decrease the friction factor. 1976 Martinus Nijhoff Publishers.Item Flow of viscous stratified fluid of variable viscosity past a porous bed(1976) Channabasappa, M.N.; Ranganna, G.To study the effects of stratification and slip velocity on the flow of fluid of variable viscosity over a permeable bed, we divide the flow into two zones called zone 1 and zone 2. Zone 1 pertains to the flow called the free flow governed by the Navier-Stokes equations in the region between the impermeable upper plate and the porous bed.. Zone 2 pertains to the flow in the bed governed by the modified Darcy Law. Using the slip velocity boundary condition, velocity distributions in zones 1 and 2 are obtained and are matched at the interface. The boundary layer thickness just beneath the permeable interface and the friction factor are also obtained. 1976 Indian Academy of Sciences.Item Effect of porous lining on the flow between two concentric rotating cylinders(1979) Channabasappa, M.N.; Umapathy, K.G.; Nayak, I.V.The effect of non-erodible porous lining on the flow between two concentric rotating cylinders is investigated using Beavers and Joseph slip boundary condition. It is shown that the shearing stress at the walls increases with the porous lining thickness parameter ?. 1979 Indian Academy of Sciences.Item A note on the computation of multiple zeros of polynomials by Newton's method(1979) Channabasappa, M.N.[No abstract available]
