Dynamics of Cattaneo-Christov heat flux and chemical reaction in Walters’ B fluid through a porous medium with Newtonian heating and heat generation/absorption

Résumé

Abstract In this work, two-dimensional boundary layer of Walters’ B fluid is examined in a porous medium along an exponential stretching sheet. The Cattaneo-Christov flux model is considered in the heat equation which describes the thermal relaxation time in the presence of Viscous dissipation and heat generation/absorption with Newtonian heating. By the means of appropriate variables, dimensionless equations which are responsible for the analysis of the problem are obtained and tackled through Homotopy Analysis Method. The result pin-point among the major findings that variation in the values of Newtonian heating and heat generation opens the path for the thermal influence to infiltrate quiescent fluid which in application contribute to the drying of electronic panels and other materials while the presence of local Weissenberg number invokes viscoelasticity impact which are essentials for polymer processing in science and engineering disciplines.
