Analysis of MHD Richardson Flow Past An Exponentially Stretched Infinite Plate with Suction and Cross-Diffusion Effects

Abstract

The present paper investigate the effects of magnetic field (MHD), Richardson and suction on an exponentially expanded infinite plate by studying the convective heat and mass transfer of a non-Newtonian incompressible viscous and electrically conducting fluid. Cross-diffusion impacts are also taken into consideration. The governing partial differential equations (PDEs) are transformed into ordinary differential equations through the application of well-posed similarity transformation variables (STVs). Thus, the transformed dimensionless equations are solved analytically by integrating factor approach and the resulting solutions are simulated with an efficient stability numerical algorithm known as Mathematica. The results are displayed in tabular and graphical forms while the effects of various parameters on the velocity, temperature, concentration, skin–friction coefficient, Nusselt and Sherwood numbers are discussed in details. It was found that velocity falls when magnetic field and suction parameters increase. Also, the temperature and nanoparticle concentration decreases as suction number rises but are enhanced as diffusion-thermo and thermal-diffusivity parameters rise. An increase in Richardson and Prandtl numbers leads to a decrease in skin-friction and upsurge in the rate of heat transportation. The results of this study can be used to advance the design, operation, and performance of various systems encountered in industrial and scientific applications.
