Effects of Activation Energy Diffusion Thermo and Nonlinear Thermal Radiation on Mixed Convection Casson Fluid Flow Through a Vertical Cone with Porous Media in the Presence of Brownian Motion and Thermophoresis

Abstract

In this paper, analyze the impact of Activation energy, Diffusion thermo and nonlinear thermal radiation of mixed convection casson fluid flow through a vertical cone with porous material in the presence of Brownian and thermophoresis has been studied. Numerical techniques, namely Runge–Kutta integration and the shooting method, were applied to obtain solutions to similarity-transformed equations governing continuity, momentum, energy and concentration. The study examined the distributions of flow velocity, temperature and concentration under the interactive effects of the fluid. The results revealed that the activation energy of the Arrhenius equation plays an important role in fluid transport mechanisms within a chemically reactive system involving the Soret effect for a low-Schmidt-number fluid. When the activation energy parameter E was greater within the range 0 < E < 5, the wall shear stress was stronger, heat transfer rate increased, and mass transfer rate decreased.
