Unsteady hydromagnetic generalised Couette flow of a viscous, incompressible and electrically conducting fluid between two horizontal parallel porous plates Darcian channel in the presence of a uniform transverse magnetic field taking Hall current and ion-slip into account in a rotating system is investigated. An exact solution of the governing equations is obtained by Laplace transform techniq...

An analysis of an oscillatory magnetohydrodynamic (MHD) convective flow of anOldroyd-B, incompressible and electrically conducting fluid through a porous medium bounded within two infinite vertical parallel porous plates is carried out. The fluid is injected with constant velocity through the stationary porous plate and simultaneously sucked with same constant velocity through the other oscilla...

Analytical solutions of an unsteady magnetohydrodynamic (MHD) flow with heat and mass transfer characteristics incompressible, viscous, electrically conducting, Boussinesq fluid over a vertical oscillating plate embedded in Darcian porous medium the presence thermal radiation are presented. The considered here is gray, absorbing/emitting radiating, but nonscattering medium. At time t > 0, tempe...

An analysis of an oscillatory magnetohydrodynamic (MHD) convective flow of a second order (viscoelastic), incompressible, and electrically conducting fluid through a porous medium bounded by two infinite vertical parallel porous plates is presented.The two porous plates with slip-flow condition and the no-slip condition are subjected respectively to a constant injection and suction velocity. Th...

The paper considers a two-dimensional mathematical model of filtration viscous incompressible fluid in deformable porous medium. is based on the equations conservation mass for liquid and solid phases, Darcy’s law, rheological relationship medium, law balance forces. In this article, equation forces taken full form, i.e. elastic properties medium are into account. aim work numerical study initi...

Due to the high performance of electronic components, the heat generated is increasing dramatically and cooling system for such components becomes one of the most important issues to dissipate heat that generated in electronic component. In the present analysis, a microchannel heat sink configuration is simulated by modelling the stacked microchannel heat sinks in macroscopic scale as if it is ...

In this paper, the passive control of flow past a semi-circular cylinder is investigated. This control is achieved by adding a porous medium between the solid obstacle and the incompressible fluid in order to reduce drag forces and regularize the flow. A vortex-penalization method is chosen to easily model the flow in the different media. Several configurations of the porous layer are investiga...
