A Reactive Hydromagnetic Internal Heat Generating Fluid Flow Through a Channel

Abstract

This paper investigates the analytical study of the temperature fluid distribution in a one-dimensional fluid flow under a magnetic field. It studies the effect of internal heat generation on the entropy generation in an exothermic reactive hydromagnetic fluid flow under Arrhenius kinetics. The fluid is assumed to be incompressible and electrically conducting flowing steadily through a channel with isothermal wall temperature. The solution is obtained taking into account a supplementary term in energy equation due to internal heat generation using the traditional perturbation method. Thermophysical aspects of the flow are presented and discussed.

Buoyancy driven flow of a reactive hydromagnetic heat generating fluid through a porous channel

“…Interestingly, our new result shall be equivalent to that of HASSAN and MARITZ, 2016 a; when the porous medium permeability parameter (  ) and buoyancy effect parameter known as Grashof number ( Gr ) are both zero to validate the solutions obtained. Table 1 displays the rapid convergence of the series solution for the constants 0 a and 0 b in equations (10) and (11) which shows the efficiency and reliability of the modified ADM. It really signifies that the series converge with sizeable iterations.…”

The effects of thermal radiation on the flow of a reactive hydromagnetic heat generating couple stress fluid through a porous channel

“…Neglecting the consumption of the reactant, the internal heat generated is assumed to be a linear relation of temperature and the thermal radiation, following [4,20], the equations governing the fluid motion and heat transfer are given in non-dimensionless form as: subject to the following boundary conditions Notably, the seventh and the last terms in Eq. 2are respectively the heat source within the flow system as stated in [36][37][38] and the compelling aspect of the radiative energy transfer as discussed extensively in [20,23,39]. Meanwhile, the Rosseland approximation for thermal radiation is given as:…”

Analysis of buoyancy driven flow of a reactive heat generating third grade fluid in a parallel channel having convective boundary conditions

“…Also, in addition to that, [36] put forward the influence of heat flux design initiated by Cattaneo-Christov on the flow across a wedge and a cone of which the effect of non-uniform wall temperatures are also examined. Other investigations on the impact of heat source are extensively discussed in [37][38][39].…”
