MHD and radiation effects on moving isothermal vertical plate
with variable mass diffusion

 

 

An analysis is performed to study the effects of thermal radiation on unsteady free convective flow over a moving vertical plate
with mass transfer in the presence of magnetic field. The fluid considered here is a gray, absorbing-emitting radiation but a non-
scattering medium. The plate temperature is raised to T'w and the concentration level near the plate is also raised linearly with
time. The dimensionless governing equations are solved using the Laplace transform technique. The velocity, temperature and concentration are studied for diŽerent parameters like the magnetic field parameter, radiation parameter, thermal Grashof number, mass Grashof number and time. It is observed that the velocity decreases with increasing magnetic field parameter or radiation parameter.
