Darcy–Forchheimer flow of micropolar nanofluid between two plates in the rotating frame with non-uniform heat generation/absorption

This article studies the Darcy–Forchheimer flow of three-dimensional micropolar nanofluid between parallel and horizontal plates in a rotating system. The micropolar nanofluid in permeable media is described by assuming the Darcy–Forchheimer model, where drenching the permeable space obeys the Darcy–Forchheimer expression. The significant influence of Brownian motion and thermophoresis has been taken in the nanofluids model. The thermal radiation impact is taken to be varying in terms of non-uniform absorption/generation for the purpose to see the concentration as well as the temperature modifications between the nanofluid and the surfaces. The leading equations are converted into a system of differential nonlinear equations and then homotopic method is used for solving the modeled equations. The other physical impacts, that is, skin friction, heat flux, and mass flux, have been studied through tables. The impacts of the porosity, rotation, and inertia coefficient analysis have been mainly focused in this research. It is observed that the higher value of Fr decay the velocity profile, while it increases the transverse velocity, and the increase in the porosity parameter γ increases the porous space, which creates resistance in the flow path and reduces the flow motion. Skin friction coefficient is observed to be larger for the strong concentration k = 0 , as compared to the case of weak concentration k = 0 . 5 . Impact of strong and weak concentrations on Nusselt and Sherwood numbers seems to be similar in a quantitative sense.
