The second-grade fluid flow due to a rotating porous stretchable disk is modeled and analyzed.A porous medium is characterized by the Darcy relation.The heat an
The effects of packing configurations on the phase transition of straight granular chute flow with two bottlenecks are studied. The granular flow shows a dilute
For the section coupled system of multilayer dynamics of fluids in porous media, a parallel scheme modified by the characteristic finite difference fractional s
