Abstract

This work examines the heat transfer on unstable MHD flow of fourth grade fluid in horizontal parallel plates. The plates are arranged so that the upper plate oscillates and moves while the lower plate is stationary. The temperatures prescribed by the plates are uniform and asymmetric. Dimensionless parameters are set to convert the governing equations to dimensionless form. Solutions for momentum and energy equations are explicitly obtained through the He-Laplace scheme. The effect of various flow parameters on velocity profile and temperature distribution is discussed using graphs. Significant results of this study show that velocity profile and temperature distribution increase with the increase in thermal radiation parameter, while the velocity and temperature distribution decrease with the increase in suction parameter. The results of this work have significant application in refrigeration industry for refrigeration, energy transfer in cooling tower, evaporation, etc.
