Impact of Brownian Motion and Thermophoresis on Casson Nanofluid flow in an Annular Microchannel
P. Venkatesh
The current examination delves into the Casson fluid flow in an annular microchannel by employing the Buongiorno model. The viscous dissipation effect and magnetic field effect is analyzed during the study in presence of two prominent slip mechanisms namely Brownian motion and thermophoresis in an annular microchannel incorporated with porous media. The governing equations are modeled based on these effects and are non-dimensionalized with the aid of non-dimensional variables. The non-dimensional equations formed are numerically computed using Runge Kutta Fehlberg 4-5 th order method and graphically illustrated. Results of this study show that velocity profiles enhance for increasing values of Casson parameter and Darcy number. Nusselt number is increasing function of Brownian motion parameter and fluid wall interaction parameter.
