Chemical Reaction on Unsteady MHD Convective Heat and Mass Transfer Past a Semi-Infinite Vertical Permeable Moving Plate with Heat Absorption

This work is focused on unsteady, two-dimensional, laminar, boundary-layer flow of a viscous, incompressible, electrically conducting and heat-absorbing fluid along a semi-infinite vertical permeable moving plate in the presence of a uniform transverse magnetic field and first order chemical reaction. The plate is assumed to move with a constant velocity in the direction of fluid flow while the free stream velocity is assumed to follow the exponentially increasing small perturbation law. The governing equations of this problem are solved using perturbation technique and the solutions for velocity, temperature, concentration, skin friction coefficient, Nusselt number and Sherwood number are obtained. The effects of various thermo physical parameters such as Schmidt number, magnetic parameter, chemical reaction parameter, solutal Grashof number, thermal Grashof number, Panduit number and heat absorption parameter over the velocity, temperature, concentration, skin friction coefficient, Nusselt number and Sherwood number are discussed through graphs and tables.
