Magnetic swirling flow and Cattaneo–Christov heat and mass flux over a stretchable cylinder: A dual stratification model

Abstract

An investigation of the influence that the Cattaneo–Christov heat and mass flux have on the whirling flow that occurs across a stretchable cylinder is being carried out in this study. This model takes into consideration the impact of a magnetic field, in addition to also taking into account heat and the diffusion of solutes. During the process of developing this mathematical model, the Navier-Stokes equation was employed to illustrate the flow that was predicted. Under the flow assumptions, the partial differential equations were derived from an approximation of the Navier-Stokes equation using the boundary layer approach. In order to make advantage of the ordinary differential equations formalism, the system is transformed via the application of similarity transformations. The Runge Kutta Felberg-45 (RKF-45) method gives an explanation of a system that does not have any dimensions. Both quantitatively and visually, the impacts of the key physical variables are shown. It is noticed that, the Swirl velocity profile decayed for higher values of magnetic parameter and Reynolds Number. Further we noticed that, the temperature fields strengthen with enhanced values of Eckert numbers (Ec1 and Ec2).
