Effects of Hall Current, Diffusion Thermos and Activation Energy on MHD Radiative Casson Nanofluid Flow with Chemical Reaction and Thermal Radiation

Abstract

In this work, we studied the impact of Hall current, diffusion thermo, and activation energy on an electrically conducting Casson nanofluid flow past a continuously stretching surface with thermal radiation, and heat generation/absorption has been explored. Transverse magnetic field with the assumption of small Reynolds number is implemented vertically. Appropriate similarity transformations are utilized to transform the governing partial differential equations into the non-linear ordinary differential equations. Numerical solutions for the dimensionless velocity, temperature and nanoparticle concentration are computed with the help of the shooting method. Through the use of graphs, the discussion will focus on the effects that the Hall current, the thermal radiation, the heat source/sink, the Brownian motion, the thermophoresis parameter, and the magnetization have on velocity, concentration, and temperature. To get an insight into the internal behavior of the emerging parameters, a numerical calculation of the local Nusselt number, the Sherwood number, and the skin friction coefficient along the x-and z axes is performed. It has been shown that the resultant flow velocity enhances with increasing hall parameter, whereas it has reduced in temperature and concentration field. The temperature diminishes with improving diffusion thermo parameters, and the opposite behavior has been observed in the case of thermal radiation.
