摘要

A hydrodynamic viscous incompressible fluid flow through a porous medium between two porous disks rotating with same angular velocity Ω about two non-coincident axes has been studied. An exact solution of the governing equations has been obtained in a closed form. It is found that the primary velocity f/(Ωl) increases and the secondary velocity g/(Ωl) decreases with an increase in either the Reynolds number Re or porosity parameter σ. It is also found that the torque at the disks η = 0 and η = 1 decreases with an increase in either σ or K~2. The heat transfer characteristic has also been studied on taking viscous dissipation into account. It is found that the rate of heat transfer at both the disks η = 0 and η = 1 decreases with an increase in σ .
