Entropy analysis of the MHD Jeffrey fluid flow in an inclined porous pipe with convective boundaries

Abstract

The present work deals with entropy generation analysis of a non-Newtonian Jeffrey fluid flow through an inclined pipe of circular cross section in the presence of uniform porous medium. The flow is subjected to constant pressure gradient and uniform magnetic field. The boundaries of circular pipe are assumed to be convective. Due to the presence of mixed convection, the underlying governing equations are nonlinear and coupled. The numerical solution of the system of governing equations is obtained. The analysis of roles played by the transport properties viz. fluid velocity and temperature is done to explore the thermodynamic entities like entropy generation number and Bejan number. The study of irreversibilities in the considered flow is analysed taking several sets of parameters, i.e., the Jeffrey fluid parameter, the Hartmann number, the Darcy number, the Grashof number, suction/injection parameter, the Brinkman number, the Prandtl number and the Biot number appearing in the problem.
