Understanding the dynamics of chemically reactive Casson liquid flow above a convectively heated curved expanse

Abstract

This paper studied the simulation of partial differential equations that model Casson fluid dynamics on a curved surface when Lorentz force, viscous dissipation, first-order chemical reaction, convection, uneven heat sink/source, and mass transmission at the wall are significant. An appropriate similarity conversion transforms the governing equations into non-dimensional ODEs. The bvp5c Matlab package is utilized to acquire the velocity, temperature, and concentration outcomes. This work aims to attain simultaneous solutions for Newtonian and non-Newtonian flow cases and analyze the reasons for deviation in flow and thermic border thicknesses. Augmenting the parametric curvature values inflates the velocity profiles and declines the thermal transmission rate. Also, the heat transport rate in the brunt of uneven heat source and viscous dissipation is extensive for non-Newtonian liquid compared with the Newtonian fluid.
