Effects Of Suction, Heat And Mass Transfer On Unsteady Magneto Hydro-Dynamics (MHD) Oscillatory Flow Of A Coupled Stress Fluid In An Asymmetric Tappered Channel

Abstract

The paper investigates Effects of Suction, Heat and Mass Transfer on Magneto Hydro-Dynamic (MHD) Oscillatory Flow of a Coupled Stress Fluid in an Asymmetric Tapered Channel. 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 dimensionless equations. The flow and the solutions for velocity, temperature and concentration distribution are obtained. The effects of flow parameters on velocity profile and temperature distribution are presented, discussed and shown graphically in details. The results of this work is in agreement with the results obtained in Sasikumar et al (2018) when s = 0. It can be concluded that Increase in s accelerates the velocity of the fluid. Increase in s declines the temperature distribution. Higher values of M retard fluid velocity. Increase in Peclet number and frequency of Oscillations decrease the temperature distribution.
