Heat and Mass Transfer on Mhd Oscillatory Flow of a Couple Stress Fluid in an Asymmetric Tapered Channel with Suction Effects

Heat and Mass Transfer on MHD Oscillatory Flow of a Couple Stress Fluid in Asymmetric Tapered Channel with suction effects. The temperatures prescribed at the channel walls are non-uniform. Magnetic field strength which is uniform is applied transversely to the channel. Dimensionless parameters are used to non-dimensionalized the governing equations to dimensionless form. Closed form solution method is used to solve the dimen sionless equations govern the flow and the solutions for velocity, temperature and concentration distribution are obtained. The effects of flow parameters on velocity profile, temperature distri bution amd concentration distribution are presented, discussed and shown graphically in details. The results of this work is in agreement with the results obtained in [11] when the suction parameter s = 0. It can be concluded that Increase in suction pa rameter s accelerates the velocity of the fluid. Increase in suction parameter s declines the temperature distribution. Higher values of Hartmann number M retards fluid velocity. Increase in Peclet number decreases the temperature distribution. And increase in radiation parameter N increases the temperature distribution.
