Transient MHD Thermally Radiating Free Convective Flow Past an Exponentially Moving and Rotating Isothermal Vertical Plate with Heat Generation, Reacting Species and Fluctuating Mass Diffusion Effects

Abstract:

The problem of transient MHD thermally radiating free convective flow past an exponentially moving and rotating isothermal vertical plate in the presence of heat generation reacting species, and fluctuating mass diffusion is examined. The flow is governed by a set of non-linear partial differential equations of the Boussinesq approximation type. In particular, the momentum equations are simplified using the 2-D fluid flow analysis in the complex plane, and the governing equations are solved using the time-dependent Homotopy Perturbation Method. Expressions for the concentration, temperature, and velocity are obtained and presented graphically. The results amidst others depict that an increase in the chemical reaction rate decreases the concentration, but causes fluctuation in the flow velocity structure; an increase in the Heat generation/absorption parameter increases the fluid temperature but causes fluctuation in the flow velocity structure.
