Effects of MHD mixed convection with non-uniform heat source/sink and cross-diffusion over exponentially stretching sheet

Abstract

Purpose The purpose of this paper is to investigate the magnetohydrodynamics mixed convection flow over an exponentially stretching surface in the presence of non-uniform heat source/sink and cross-diffusion. Adequate non-similar transformations are used to transform governing mixed convection boundary layer equations to dimensionless form. Design/methodology/approach These dimensionless partial differential equations are solved by using implicit finite difference scheme in conjunction with Quasi-linearization technique. Findings The effects of admissible parameters such as Eckert number (Ec), the ratio of buoyancy forces parameter (N), non-uniform heat source/sink, Soret and Dufour numbers on flow, temperature and concentration distributions are discussed and analysed through graphs. In addition, the results for skin friction coefficient, Sherwood number and Nusselt number are presented and discussed graphically. Originality/value In literature, no research work has been found in similar to this research paper.

Impact of Activation Energy and Temperature-Dependent Heat Source/Sink on Maxwell–Sutterby Fluid

“…Various researchers have studied the importance of heat generation/absorption and variable thermal conductivity for the purpose of heat transfer analysis. Patil et al [15] contemplated the fluid above an exponentially stretching surface along with MHD and nonuniform heat source/sink. ey found that temperature profile diminishes by escalating the thermal relaxation effect.…”

Modeling entropy generation of magnetohydrodynamics flow of nanofluid in a porous medium: a review

“…However, as Prandtl and Deborah’s numbers increased, the temperature species decreased. While Patil et al (2018) studied MHD-mixed convection flow across an exponentially stretched area with a nonuniform sink/heat source and cross-diffusion. The results reveal that, as the magnetic effect is reduced, the velocity profile improves.…”

Computational analysis of bio-convective eyring-powell nanofluid flow with magneto-hydrodynamic effects over an isothermal cone surface with convective boundary condition

“…Patil et al [ [67] , [68] , [69] , [70] , [71] ] examined the behavior of a non-Newtonian fluid model under convective boundary situations and evaluated it numerically by employing the finite difference quasilinearization method. Additionally, Patil et al [ [72] , [73] , [74] , [75] , [76] ] looked at the mass and heat transfer of various geometries and diverse nanoparticle types.…”
