Theoretical Study of Eyring-Powell Nanofluid Flow in Darcy-Forchheimer Porous Medium over a Radial Stretching Surface

Abstract

This article investigates the flow dynamics of an Eyring-Powell nanofluid over a radially stretching surface. A revised zero-mass flux condition is applied, along with the effects of convective heat transfer and viscous dissipation. The influence of thermophoresis and Brownian motion is also considered. The mathematical formulation is developed under the boundary layer approximation, where the governing partial differential equations are transformed into a system of nonlinear ordinary differential equations using appropriate similarity transformations. These resulting equations are then solved numerically using the bvp4c. The study examines the velocity, temperature, and concentration profiles for various governing parameters, including the magnetic parameter, fluid parameter, Prandtl number, Biot number, and Eckert number. The findings reveal
that variations in the fluid parameter have a significant impact on velocity, temperature, and concentration distributions.
