Effects of Modified Magnetic Field on Unsteady Flow of Viscoelastic Stratified Fluid Between Two Parallel Inclined Riga Plates with Viscous Dissipation

Abstract

The study in this paper investigates the effect of modified magnetic field on unsteadyflowofviscoelastic stratified fluid between two parallel Riga plates inclined at an angle. The magneticfield is generated by the upper and lower Riga plates which are kept stationary. These Rigaplatesare kept at different temperature which decay with time with fluid density and viscosityareconsidered to be variable among different layers within the medium. The non-linear PDEs that govern the flow problem are transformed into non-dimensional  PDEs and solved numericallyusing explicit finite difference scheme. Maple 23 is used to implement and simulate these schemesand the  result are analyzed and presented inform of graphs. It is established that the effect ofReynolds number, viscoelastic parameter,  stratification parameter and Prandtl number onthevelocity and temperature distribution are subdued by modified magnetic field.
