MFD Casson-Williamson fluid flow across an inclined stretching surface with radiative heat

Abstract

This study investigates the magneto fluid dynamic (MFD) Casson-Williamson fluid (CWF) flow of reaction with chemicals and the effect of thermal radiation on an inclined plane at an angle  on a stretching surface. Our main goal is to understand the impact of the magnetic field and the Lewis number on the transfer of heat. The framework involves converting partial differential equations (PDEs) into ordinary differential equations (ODEs) using suitable techniques. ODEs are solved using MATLAB through the BVP4C method, which employs a finite difference approach. The comparable inferences that were considered for the Williamson and Casson fluid are presented in graphs and tables. Moreover, the research examines the effects of key dimensionless parameters on the flow, heat and mass transfer characteristics of the system. An increase in the magnetic parameter reduces fluid velocity due to the Lorentz force while enhancing energy generation within the flow. Higher Prandtl number decrease temperature field and intensify fluid motion buoyancy effects. The analysis covers heat generation in MFD CWF, with a detailed assessment of the transfer of heat on a stretched surface in an inclined plane at an angle with a permeable surface.
