Irreversibility Analysis of Magnetohydrodynamic Flow over an Impulsively Started Plate

Abstract

The aim of the present paper is to analyze the irreversibility effects in magnetohydrodynamic flow over an impulsively started plate. The transformed dimensionless governing equations for the flow and heat equations are solved using the Laplace transform technique. The velocity and the temperature profiles are obtained for the parameters involved in the problem. The expression for the entropy generation number and the Bejan number are computed using the velocity and the temperature expressions. The graphs are plotted for velocity, temperature, entropy generation number and Bejan number and are discussed. doi:10.14456/WJST.2014.56
