Symmetric and Non-Symmetric Flows of Burgers’ Fluids through Porous Media between Parallel Plates

Unidirectional unsteady flows of the incompressible Burgers’ fluids between two infinite horizontal parallel plates are analytically studied when magnetic and porous effects taken into consideration. The fluid motion is induced by plates, which move in their planes with time-dependent velocities. Exact general expressions established both for dimensionless velocity shear stress fields as well corresponding Darcy’s resistance channel using Laplace transform. If equal velocities same direction, becomes symmetric respect to mid-plane them. Otherwise, its non-symmetric. To bring light behavior fluid, profiles versus spatial variable time evolution presented asymmetric case. Finally, comparison, similar graphical representations together Oldroyd-B fluids. For large values t, expected, different almost identical. against y also graphically represented flow at t. influence field on revealed discussed.
