Mathematical study of MHD Convective flow with chemical reaction through a porous medium in a vertical wavy channel
Abstract
In this work, we examine how transitory free connective heat and mass transfer flow over a porous media in a vertical wavy channel is impacted by chemical reactions and radiation absorption. The oscillatory flux in the flow zone is the cause of the unsteadiness in the flow. The Laplace transformation approach is used to get the analytical solutions for the governing equations. Analysis is done on the profiles of temperature, concentration, and velocity. The governing parameters are varied, and the resulting expressions for the velocity, concentration, shear stress, and rate of heat and mass transfer are examined.
