Activation energy and cross-diffusion effects on 3D rotating nanofluid flow in a Darcy–Forchheimer porous medium with radiation and convective heating

Abstract The goal of the current study is to discover the impact of cross diffusion effects, activation energy, thermal radiation, and convective heating on three-dimensional doubly diffusive convective nanoliquid flow over a rotating surface in a Darcy–Forchheimer porous domain with heat generation. The governing model (partial differential equations) are solved numerically after being converted by similarity transformation into a nonlinear ordinary differential system. The numerical solutions are obtained for various combinations of effects involved in the physical model. The skin friction and mass and heat transferral rates are also computed. The activation energy is more pronounced on solutal transport than that of on thermal transport. The heat transfer is suppressed by strengthening the values of the inertia parameter and the rotational parameter.
