要約

Fully developed laminar flow of a viscous incompressible fluid in an annular region between two coaxial cylindrical tubes filled with a porous medium of variable permeability is studied when the permeability of the porous medium varies with the radial distance. Analytical solutions of the problem for three special cases of permeability variation are derived, and relevant quantities such as velocity, volumetric flow rate, and average velocity and stress on the boundaries are obtained and exhibited graphically. The influence of the various parameters on the flow are discussed. It is found that the variation of permeability has considerable influence on the flow quantities. The authors have not come across such results in the existing literature.
