Abstract

The present study’s main focus is regarding the physical properties of a two-dimensional (2D) magneto-hydrodynamic boundary layer non-Newtonian Casson fluid flow that moves due to an exponentially expanding surface with a mixed convection heat transfer mechanism. In the hydrodynamic flow and heat transmission process, the combined impact of thermal radiation and magnetic field influence is explored. The internal heat generation owing to the fluid motion or a very fluid viscosity is not taken into account. The Chebyshev spectral method (CSM) is employed in this work due to its ability, accuracy, and ease of obtaining the solution for non-linear system of ordinary differential equations (ODEs). This method is an approximate method that can usually obtain the solution in a series form. The mixed convection impact is incorporated in our problem. The results are graphed to help comprehend the many physical parameters that arise in the problem. Graphical results uncover that the speed liquid stream is lessened when reinforcing both the Casson boundary and the Hartmann number, while converse attributes are applied for the Grashof number and the radiation boundary. Finally, a comparison of our current results with previously published work on several particular situations of the problem reveals that they are in excellent agreement.

Summary

Introduction

Accepted: 27 January 2022Research issues in regards to the non-Newtonian fluid movement and heat transport in the Casson model as a result of an extending surface with a given temperature have an assortment of uses in the design and a few modern assembly processes, in the most recent couple of years. A non-Newtonian fluid with yield stress is known as a Casson fluid [1,2,3,4]. These manufacturing processes may include hot rolling, glass fiber, wire drawing, the expulsion of plastic sheets, extraction of raw petroleum from oil-based commodities and paper creation. Studies of the non-Newtonian Casson fluid have their importance in engineering, as well as in scientific areas [5,6,7,8,9,10]. The linear and non-linear differential equations, the integral equations, and the integro-differential equations have all been solved using these
