Entropy Generation in Couette Flow Through a Deformable Porous Channel
2019
The present study examines the entropy generation on Couette flow of a viscous fluid in parallel plates filled with deformable porous medium. The fluid is injected into the porous channel perpendicular to the lower wall with a constant
velocity and is sucked out of the upper wall with same velocity .The coupled phenomenon of the fluid flow and solid
deformation in the porous medium is taken in to consideration. The exact expressions for the velocity of fluid, solid displacement and temperature distribution are found analytically. The effect of pertinent parameters on the fluid velocity,
solid displacement and temperature profiles are discussed in detail. In the deformable porous layer, it is noticed that the
velocity of fluid, solid displacement and temperature distribution are decreases with increasing the suction/injection velocity parameter. The results obtained for the present flow characteristic reveal several interesting behaviors that warrant
further study on the deformable porous media. Furthermore, the significance of drag and the volume fraction on entropy
generation number and Bejan number are discussed with the help of graphs.
