Magnetohydrodynamic Radiating and Chemically Reacting Fluid over an Infinite Vertical Surface

Abstract

ABSTRACT: An analysis is carried out to study the nonlinear MHD flow with heat and mass transfer characteristics of an electrically conducting, incompressible, viscous and Boussinesq fluid over a vertical oscillating porous permeable plate in presence of homogeneous chemical reaction of first order and thermal radiation effects. Here considered fluid is a gray, absorbing/emitting radiation, but a non-scattering medium. At time  , the plate temperature and concentration levels near the plate raised linearly with time. An approximate numerical solution for the flow problem has been obtained by solving the governing boundary layer equations using a closed analytical method. It has been found that, the fluid velocities as well as concentration profiles were decreased when the chemical reaction parameter increased. An increase in conduction radiation parameter is found to escalate temperatures and shear stress in the regime. Applications of the study arise in materials processing and solar energy collector systems.
