Abstrakty
A hydrodynamic viscous incompressible fluid flow through a porous medium between two porous disks rotating with same angular velocity [...] 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 [...] increases and the secondary velocity [...] decreases with an increase in either the Reynolds number Re or porosity parameter [...]. It is also found that the torque at the disks [...] and [...] decreases with an increase in either [...] or . The heat transfer haracteristic has also been studied on taking viscous dissipation into account. It is found that the rate of heat transfer at both the disks [...] and [...] decreases with an increase in [...].
