ENTROPY GENERATION IN A MAGNETOHYDRODYNAMIC FLUID FLOW THROUGH A VERTICAL DEFORMABLE POROUS MEDIUM

Abstract

This project investigates entropy generation in a magnetohydrodynamic (MHD) fluid flow through a vertical deformable porous medium. The model equations for the solid displacement, velocity, temperature and entropy generation number governing the fluid flow in the porous medium in their dimensional form were converted to non-dimensional form. The Adomian Decomposition Method (ADM) was applied to obtain the recursive scheme for each of the nondimensional equations. The recursive scheme obtained solves the non-dimensional differential equations. The package MATHEMATICA was used to implement the scheme. The solutions obtained were also represented graphically to further explain the behaviour of the MHD fluid with varying conditions. The results obtained showed that entropy generation increases with increase in the viscous dissipation parameter.
