Unsteady Chemically Radiating Magneto-Hydrodynamics (Mhd) Oscillatory Flow In A Vertical Porous Channel With Suction/Injection Effects

Abstract

Unsteady chemically radiating magneto-hydrodynamics (MHD) oscillatory flow in a vertical channel with Suction/injection effects have been investigated. The flow is laminar and incompressible. The temperatures prescribed at the channel walls are non – uniform. A uniform magnetic field is applied transverse to the channel. Non – dimensional parameters are used to non – dimensionalized the governing equations to dimensionless form. Closed form solution method is used to solve the dimensionless equations that govern the flow and the solutions for velocity, temperature and concentration distribution are obtained. The influence of flow parameters as they affect the velocity profile, temperature distribution, species concentration, skin friction, Nusselt number and Sherwood number are analysed and shown graphically in detail using MATLAB. Out of many results, it is concluded that the suction/injection parameter accelerates the velocity and elevates the temperature distribution and species concentration.
