Influence of Magnetic Field and Porous Medium on the Steady State and Flow Resistance of Second Grade Fluids over an Infinite Plate

The main purpose of this work is to completely solve two motion problems some differential type fluids when velocity or shear stress given on the boundary. In order do that, isothermal MHD motions incompressible second grade over an infinite flat plate are analytically investigated porous effects taken into consideration. fluid due moving in its plane with arbitrary time-dependent applying a fluid. Closed-form expressions established both for dimensionless and fields Darcy’s resistance corresponding first motion. has been immediately obtained using perfect symmetry between governing equations non-trivial stress. Furthermore, results provide exact general solutions through media. Finally, illustration, as well their use engineering applications, starting and/or steady state technical relevance provided, validation graphically proved. influence magnetic field medium flow underlined discussed. It was found that declines increases presence medium, respectively. addition, earlier medium.
