A magnetohydrodynamic convective unsteady flow past a uniformly accelerated infinite isothermal vertical plate in the presence of variable mass diffusion is analyzed using the Laplace transform technique. The plate temperature is raised to [...] and the concentration level near the plate is raised linearly with time.The velocity profiles are studied for different physical parameters such as the magnetic field parameter, thermal Grashof number, mass Grashof number and time. It is observed that the velocity increases with increasing values of the thermal Grashof number or mass Grashof number. It is also observed that the velocity increased with decreasing the magnetic field parameter.

An exact analysis is performed to study the unsteady flow past an infinite vertical oscillating plate with variable temperature and mass diffusion, in the presence of thermal radiation and homogeneous chemical reaction of first order. The fluid considered here is a gray, absorbing-emitting radiation but a non-scattering medium. An exact solution to the dimensionless governing equations has been obtained by the Laplace transform method, when the plate is oscillating harmonically in its own plane. The effects of velocity, temperature and concentration are studied for different physical parameters like phase angle, radiation parameter, chemical reaction parameter, Schmidt number, thermal Grashof number, mass Grashof number and time. It is observed that velocity increases with decreasing the phase angle. It is also observed that velocity increases with decreasing the thermal radiation parameter or chemical reaction parameter.

An exact solution of an unsteady flow past an uniformly accelerated infinite vertical plate with prescribed uniform heat and mass flux is analyzed. The temperature of the plate and concentration level near the plate are raised at a uniform rate. The dimensionless governing equations are tackled using the usual Laplace-transform technique. The velocity, temperature and concentration fields are studied for different physical parameters such as the Prandtl number, thermal Grashof number, mass Grashof number, Schmidt number and time. It is observed that the velocity increases with increasing values of the thermal Grashof number or mass Grashof number. It is also observed that the velocity increases with decreasing values of the Schmidt number.
