Cattaneo-Christov heat and mass transmission of dissipated Williamson fluid with double stratification

Abstract

The vast significance and applications in various industrial works such as heat and cooling process, chemical reactors, food storage systems and several medical works motivated the author to conduct this type of study. The aim of this paper is to inspect the two-dimensional incompressible magnetohydrodynamic flow of Williamson fluid through a stretching sheet. The Cattaneo-Christov temperature and concentration flow is considered with the effects of double stratification and viscous dissipation. The leading nonlinear partial differential equations of flow are transformed into ordinary differential equations by means of renowned similarity transformations and the solutions of flow problem are obtained by means of bvp4c method on MATLAB software. The Williamson fluid parameter depending on time relaxation and declines the fluid motion. The motion of fluid slowed down due to Hartman number. The mass and heat flow is noted to be decline due to thermal and solutal relaxation parameters. The rises in stratification coefficient reduce the mass and heat transferal rate.
