Thermal aspects of multiple slip and Joule heating in a Casson fluid with viscous dissipation and thermo-solutal convective conditions

Abstract

Recently, in various biological processes such as endoscopic medication, blood pumping from the heart to different parts of the body, food supply, and in maintaining heat transfer phenomenon, slip plays a significant part in all aspects. Therefore, a study is aimed to enlighten the significance of multiple slips with Joule heating in a mixed convective Casson fluid. The flow regime is induced by the thermal radiation, chemical reaction and nonuniform heat source/sink in order to accomplish the heat and mass transportation. The modeled equations generated from the physical problem are transmuted into ordinary differential frameworks. The transformed system of equations was solved by means of numerical technique named Runge–Kutta Fehlberg method. The numerical results for involved engineering parameters like Joule heating, Eckert number, thermal, mass and velocity slip parameters for temperature, velocity and fluid concentration are analyzed by graphs using MATLAB. The numerical values for the drag force and Nusselt number are keenly observed and concluded that slip controls the flow closer to the boundary layer. Furthermore, magnetic factor decreases the velocity field and Eckert number enhances the temperature filed.
