Abstract

An exact solution of thermal radiation and chemical reaction on unsteady free convective flow over a moving vertical plate with mass transfer in the presence of magnetic field is studied. The fluid considered here is a gray, absorbing-emitting radiation but a non-scattering medium. The temperature is raised linearly with time and concentration level near the plate are raised uniformly. The dimensionless governing equations are solved using the Laplace transform technique. The velocity, temperature and concentration are studied for different parameters like the magnetic field parameter, radiation parameter, chemical reaction parameter and time. It is observed that the velocity decreases with increasing magnetic field parameter or radiation parameter.

Key Words: gray, radiation, magnetic field, chemical reaction, vertical plate.
