Author(s): Rajput USand Shareef M

An unsteady MHD free convective flow of an incompressible, electrically conducting, viscous fluid along an infinitely long vertical plate with an impulsive motion in the presence of heat source and homogeneous binary chemical reaction in a rotating system is studied here. The dimensionless form of governing equations is obtained and solved analytically with the help of Laplace transform method. The solutions obtained for concentration, temperature and velocity distribution are analyzed graphically. The numerical values of the skin friction at the plate are shown in the table. It is noticed that for a strong magnetic field the flow pattern is affected significantly by Hall current at a different rotation. The results obtained may be useful for applications in the area related to the structure of rotating magnetic stars, the solar physics which deals the sunspot development, and the solar cycle, etc.
