Abstract

The analysis of hydromagnetic inherent irreversibility of reactive third-grade poiseuille flow and incompressible fluid heat properties of a variable viscosity with convective cooling in fixed plates is investigated. The heat dissipation of reactive exothermic chemical in a uniform magnetic field moves past fluid in a porous medium in an irreversible mode and the entropy is created continually in the system within the channel stimulated by bimolecular chemical kinetic. The heat convective transfer at the walls surfaces with the immediate surrounding follows Newton’s law of cooling. The dimensionless nonlinear equations are solved by the method of weighted residual (WRM). The results are used to obtain the Bejan number of the system and the entropy generation rate. The effects of the selected relevant parameters on the flow, entropy generation and Bejan number are demonstrated graphically and conferred with reverence to the parameters
