Laminar flow in channels with porous walls
WebbThe steady two dimensional laminar flow of a viscous incompressible and electrically conducting fluid through a channel of rectangular cross-section in the presence of a transverse magnetic field is discussed when the fluid is being withdrawn through both the walls of the channel at the same rate. Webb7 feb. 2012 · [7] Berman was the first to investigate the effects of wall porosity in a channel, followed by Terrill and Shrestha, whose study included walls of different permeability.However, Beavers and Joseph were the first to account for the material properties of permeable walls in fluid flow problems [Beavers and Joseph, …
