The analysis of a reactive hydromagnetic internal heat generating poiseuille fluid flow through a channel

Abstract

In this paper, the analysis of a reactive hydromagnetic Poiseuille fluid flow under different chemical kinetics through a channel in the presence of a heat source is carried out. An exothermic reaction is assumed while the concentration of the material is neglected. The Adomian decomposition method together with Pade approximation technique are used to obtain the solutions of the governing nonlinear non-dimensional differential equations. Effects of various physical parameters on the velocity and temperature fields of the fluid flow are investigated. The entropy generation analysis, irreversibility distribution ratio, Bejan number and the conditions for thermal criticality for different chemical kinetics are also presented.

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

“…However, from engineering and industrial applications, the effect of heat transfer on a fluid flow within parallel plates cannot be totally neglected as recently discussed in [32]. In support of that, the estimation of heat transfer depends on temperature which raises the interaction of moving fluid and thus the conduct of the internal energy of the flow system is presented in [33]. Other studies showing the effects of internal heat on the fluid flow include [34] where investigation of free convective flow of fluid with heat source/sink between vertical parallel porous plates.…”

“…Both plates are subjected to the impact of heat source which is a linear relation of temperature. Disregarding the consumption of the reacting viscous fluid, the equations controlling the fluid momentum and energy in non-dimensional form using [20,27,33,40] may be written as:…”

“…Also, R stands for the universal gas constant, Q 0 represents the dimensional heat generation coefficient, h is the heat transfer coefficient, T 0 is the wall temperature and E G is the rate of entropy generation in non-dimensionless form. It is worthy to note that the last term in the momentum equation is the additional term to extend the study in [40] by examining the impact of buoyancy force as in [27] and the final term in energy equation is resulting from heat source [33,34,39].…”

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:…”

On a new block method for an MHD nanofluid flow with an exponentially decaying internal heat generation

“…In Reference 7, internal heat generation was explained as heat generated within a body from a chemical, electrical, or nuclear process. The analysis of a reactive hydromagnetic internal heat‐generating poiseuille fluid flow through a channel was investigated in Reference 8. A new model for internal heat generation in nanofluid flow due to a stretching sheet in a porous medium was given in Reference 9.…”
