On the Flow of a Dusty Gas through a Channel over a Porous Layer Saturated with a Dusty Gas

Abstract:

Flow through a free-space channel underlain by a porous layer is considered. Both regions are saturated with particle-laden fluid driven by the same pressure gradient. Velocity distribution in both regions are derived and velocity and shear stress conditions at the interface are obtained. Effects of mixture and porous medium parameters on the flow characteristics are investigated in Cartesian and in curvilinear coordinates. Analysis shows that when the dust-phase velocity is the product of a position function and the fluid-phase velocity, the particle number density does not influence conditions at the interface between the two layers.
