Second Law Analysis for Radiative Magnetohydrodynamics Slip Flow for Two Different Non-Newtonian Fluid with Heat Source

Abstract

The present article embraces an entropy analysis on Newtonian and Non-Newtonian fluid due to melting stretching surface in the presence of inclined MHD, non-liner chemical reaction implanted in porous medium with heat source and non-uniform radiations. Also second law analysis and three different fluids namely Casson, Williamson and Viscous fluids has been taken into an account. This work is not priorly performed including the concept of Entropy generation of above mentioned three fluids. Utilizing the exercise of MATLAB tool along with algorithm of Runge-kutta technique the arithmetic manipulations for the thermotic equations, mass concentration and momentum equations are executed. Influence of numerous pertinent parameters are investigated on the flow, heat and mass transfer concepts and are demonstrated graphically. The analysis discovered that Entropy generation is improved for Magnetic field parameter M, porosity parameter Kρ as well as on the inclined magnetic field angle α but the contrary effects are observed on the amount of slip parameter.

MHD micro polar fluid flow over a stretching surface with melting and slip effect

“…Govindarajan et al 38 discussed slip and mass transfer effects in a vertical channel under consideration of heat source and radiation. Olkha and Dadheech 39 , 40 discussed entropy analysis for MHD flow for different non-Newtonian fluid caused by a stretching sheet with slip effect and heat source. Dadheech et al 41 investigated MHD flow for Casson fluid caused by a stretching sheet with slip effect.…”

“…The appropriate boundary condition (Olkha et al 39 ) for flow, concentration and temperature is where and are surface velocity, microrotation velocity, surface condition parameter, velocity slip, thermal slip and concentration slip parameter, microrotation viscosity, latent heat, heat capacity of solid surface, melting temperature, solid surface temperature, fluid concentration at the wall, free stream temperature, and suction velocity respetively. It is assumed that where as a reference length.…”

Heat transfer characteristics in non‐Newtonian fluid flow due to a naturally permeable curved surface and chemical reaction

“…It was observed that the pace of the flow boosted with the rising value of the melting parameter. Olkha and Dadheech 51 have considered melting heat transport in radiative slip flow of a combination of two different non‐Newtonian fluids owing to a permeable stretching surface under magnetic field and heat source effects. Gireesha et al 52 have investigated melting heat transport phenomena in dusty Casson flow owing to a stretching sheet along with the magnetic field effect, considering the Cattaneo–Christov heat flux model.…”
