Magnetohydrodynamic Casson Fluid Flow over an Infinite Vertical Plate with Chemical Reaction and Heat Generation

Abstract

In this paper, the fluid examined was electrically conducting. The presence of a uniform transverse magnetic field at the plate was also taken into cognizance. The flow was governed by a modeled coupled nonlinear system of partial differential equations (PDEs) in dimensional form which was transformed into non-dimensional form using some non-dimensional variables. Explicit finite difference method (EFDM) was employed to approximate the fluid velocity, temperature and concentration. The effects of embedded thermo physical parameters of engineering interests on the flow quantities viz. velocity, temperature, concentration field presented through graphs were also examined through a series of numerical experiments and discussed. During the course of the numerical computations, it was found that heat generation has a tendency to enhance the fluid velocity as an opposite result is seen with chemical reaction parameter. A comparison was conducted of present results with the previous literature to show the accuracy of the results.

Mathematical modeling of steady MHD Casson fluid flow with stretching porous walls in existence of radiation, chemical reaction, and thermal diffusion effect

“…Naduvinamani and Shankar Usha 27 have worked on unsteady MHD squeezing Casson fluid with the impact of Joule dissipation and thermal radiation. Omokhuale and Jabaka 28 have observed the conclusion of chemically reactive impact and heat generation over an electro conducting infinite vertical plate of non‐Newtonian Casson fluid (shear‐thinning) flow. Prasad et al 29 analyzed the axisymmetric mixed convective MHD Casson nanofluid flow in the existence of heat source (or sink) impact and surface with velocity slip borderline conditions over a stretched variable thickened rotating disk along with thermo buoyancy and viscous dissipative effects.…”
