Abstract

An analysis is carried out to study the nonlinear MHD flow with heat and mass transfer characteristics of an incompressible, viscous, electrically conducting and Boussinesq fluid over a vertical oscillating porous permeable plate in presence of homogeneous chemical reaction of first order and thermal radiation effects. The fluid considered here 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, when the chemical reaction parameter increased, the fluid velocities as well as concentration profiles were decreased. 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.
