Effects of MHD and slip on heat transfer boundary layer flow over a moving plate based on specific entropy generation

Abstract

In this article, combined effects of magnetohydrodynamics (MHD) heat transfer flow under the influence of slip over a moving flat plate are investigated. Effects of entropy generation are also examined. A set of non-dimensional resulting equations are solved by means of Bvp4c Matlab package. The role of flow parameters like magnetic parameter and slip parameter on flow velocity profile and temperature profile are presented and elaborated through graphs. The expressions for entropy generation and flow against Bejan number are also examined. The obtained results reveal that for various values of slip parameter, the Bejan number (Be) decreases for λ > 1, whereas opposite behaviour is noted for λ < 1.

Heat transfer in an unsteady vertical porous channel with injection/suction in the presence of heat generation

“…MATHEMATICA was used to execute the program for the mathematical schemes in Equations (7) and (8). The parameters M = 0.5, Gr = 0.5, Re = 1, A = 1, y = 0.02, t = 0.5, t = 50 are kept unchanged through the study unless otherwise stated.…”

“…In real-life processes, entropy generation provides explanations for the thermal equilibrium and properties of physical processes. The evolution of entropy as a result of irreversibility can manifest in terms of entropy generation which is always against all thermal systems, for instance, energy storage, insulation, and geothermal energy system [8]. Since the temperature difference of entropy is dissipation, it can therefore be studied via thermodynamics second law [9].…”

Reproducing kernel Hilbert space method based on reproducing kernel functions for investigating boundary layer flow of a Powell–Eyring non-Newtonian fluid

“…Nanofluid has been obtained to possess enhanced thermophysical features such as thermal conductivity, thermal diffusively, viscosity and convective heat transfer coefficients compared to those of base fluids like oil or water [21]. For more details see [19][20][21][22][23][24][25][26][27][28][29][30][31].…”

Free convective MHD micropolar fluid flow with thermal radiation and radiation absorption: A numerical study

“…In recent, Mishra et al [14][15][16][17][18][19] have studied on the various aspects of flow phenomena in micropolar fluid and their concluding remarks contributes significant approach in different field of research. Moreover, Ellahi et al [20][21][22][23][24] have investigated more studies on the MHD flows of various fluids in different geometries. MHD boundary layer flow over a permeable stretching sheet with entropy generation is reported by Bhatti and Rashidi.…”
