Impacts of joule heating with Cattaeno- Christove heat flux model in a MHD flow of Erying- Powell fluid on a Riga plate

Abstract

This article is related to analysing the consequences of joule heating and thermal (hot) radiation on the limit layer stream of a non-Newtonian liquid (Powell-Eyring fluid) while electro transversal magnetic field is present and Cattaneo Christov double diffusion via a convectively heated Riga Plate. The effects of the coefficient of thermophoresis and Brownian motion on joule heating are included in this mathematical model. In this paper, we introduced a new condition namely zero mass flux. A rectangular coordinates system is being employed for the flow equations to get the momentum, energy equations and concentration equations mathematically. By employing a similarity transformation, established (partial differential equations) PDE is reduced into an ordinary differential equations ODE. This method is integrated with the Runge-Kutta RK technique to solve this nonlinear ODE numerologically. With Graph, we show different parameters of velocity and temperature etc. Skin friction, with the help of a graph we can also inspect the Nusselt number and Sherwood number in detail. While studying we noticed that the increase of Hartmann number and fluid parameter is caused to increases in fluid velocity and thickness of the boundary layer. Prandtl number values are increases while decreasing in temperature of flowing fluid and concentration distribution of flowing fluid. This exploration motivates the previous research, and for further study, it gives a platform to analyse on flow past of nanofluid over a Riga plate.
