Upper-convected flow of Maxwell fluid near stagnation point through porous surface using Cattaneo-Christov heat flux model

Abstract

The aspiration of this study is to concentrate on a numerical inspection of the magnetohydrodynamic stagnation point flow of Maxwell fluid over upper-convected Joule heating effects by engaging the Cattaneo-Christov heat flux model. For motivation of the problem, the influence of heat and mass transfer are taken into account. The set of proposed model nonlinear partial differential equations is renovated into a couple of ODEs by exercising helpful similarity functions. Numerical elucidation of these model ODEs is obtained by the well-known scheme shooting approach, and the acquired numerical outcomes are compared with the Bvp4c command of MATLAB. Impression of several emerging parameters on velocity f′, temperature θ′ and concentration φ′ field are explained by graphs and tables. We observed that the velocity distribution reduced for the ascending value of the Deboreh number Γ magnetic number M. The enrichment in the values of the Prandtl number Pr decreased in the temperature profile. In-depth discussion is had regarding how various physical factors affect flow and heat transfer characteristics.
