Three-dimensional flow past a porous vertical plate in a porous medium with sinusoidal suction and permeability in the presence of thermal diffusion

An analytical solution, based on the asymptotic series expansion method, for the problem of a fully developed chemically reactive laminar three-dimensional flow through a porous vertical infinite plate in a porous medium with sinusoidal permeability as suction in the existence of appreciable radiation is presented. The effects of the physical parameters entering into the problem on the flow and transport characteristics are studied and demonstrated through graphs. The flow is three-dimensional due to sinusoidal suction as well as porosity. It is found that concentration of the fluid rises due to thermal diffusion (Soret) effect. Furthermore, it is seen that fluid velocity is increased for increasing thermal diffusion effect. Also, viscous drag at the plate is increased under the Soret effect.
