Chemical Reaction and Thermal Radiation Effects on MHD Mixed Convection over a Vertical Plate with Variable Fluid Properties

Abstract

This article investigates the magnetohydrodynamic mixed convective heat, and mass transfer flow of an incompressible, viscous, Boussinesq, electrically conducting fluid from a vertical plate in a sparsely packed porous medium in the presence of thermal radiation and an nth order homogeneous chemical reaction between the fluid and the diffusing species numerically. In this investigation, the fluid and porous properties like thermal and solutal diffusivity, permeability and porosity are all considered to be vary. The governing non-linear PDE's for the fluid flow are derived and transformed into a system of ODE's using an appropriate similarity transformation. The resultant equations are solved numerically using shooting technique and Runge-Kutta integral scheme with the help of Newton-Raphson algorithm in order to know the characteristics of the fluid for various non-dimensional parameters which are controlling the physical system graphically. The results of the numerical scheme are validated and a numerical comparison has been made with the available literature in the absence of some parameters and found that in good agreement.

Effect of radiation and viscous dissipation using the Galerkin method over a vertical porous plate with variation in temperature

“…Reddy et al 16 analyze and determine the unsteady MHD, stream of a sticky, nonpressable, and electrically insulating moisture/fluid labeled Kuvshinski-fluid over an endless perpendicular porous sheet, of a homogeneous chemical reaction and radiation absorption, as well as a heat source/sink. Suresh Babu and colleagues [17][18][19] studied about variable fluid properties through a vertically heated plate embedded in a porous medium. Stream point stagnation of a nonpolar flow over an exponentially curved surface is investigated by Kempannagari et al 20 heat and mass transfer properties of an unsteady MHD boundary layer flow through, with pores over a stretched sheet in the presence of reaction kinematics applications, and thermophoresis, thermal, and irregular heat generation, are studied by Reddy et al 21 Kumar et al 22 investigated the heat consequences of a viscous radiating stream through a penetrable screen in the process of generated field of magnetic.…”

Hall and Rotation Effects on Radiating and Reacting MHD Flow past an Accelerated Permeable Plate with Soret and Dufour Effects

“…2022; 19(5): 2879 2 of 17 reaction has been discussed by Reddy [8]. Babu et al [9] presented the effects of chemical reaction and thermal radiation on MHD mixed convection flow over a vertical plate with variable fluid properties. Reddy [10] studied the impact of chemical reaction on a transient MHD mixed convection flow with mass transfer past an impulsively fixed infinite vertical plate under the effect of thermal radiation.…”
