Three-dimensional rotating Darcy-Forchheimer flow with activation energy

Purpose The purpose of this study is to study flow caused by rotating frame. Effects of Darcy-Forchheimer and porous medium are considered to study velocity field. Concentration field is discussed in presence of activation energy. Darcy-Forchheimer in a rotating frame is examined. Flow because of stretched sheet fills the porous space. Binary chemical reaction is entertained. Resulting system is numerically solved. The plots are arranged for rotational parameter, porosity parameter, coefficients of inertia, Prandtl number and Schmidt number. It is revealed that rotation on velocity has opposite effects when compared with temperature and concentration distributions. Skin friction coefficients and local Nusselt and Sherwood numbers are numerically discussed. Design/methodology/approach Darcy-Forchheimer in a rotating frame is examined.

It is revealed that rotation on velocity has opposite effects when compared with temperature and concentration distributions. Skin friction coefficients and local Nusselt and Sherwood numbers are numerically discussed. Findings The major findings here are as follows: an addition in porosity lambda causes decay in velocity f '(eta) while there is opposite behavior for temperature theta(eta) and concentration phi(eta) fields. theta and phi via beta have similar results qualitatively. There is an opposite behavior of Pr on temperature and concentration. Inverse behavior of lambda on phi and wall mass flux is noted. Concentration phi is decreasing function of reaction rate constant sigma. Skin friction coefficient has similar qualitative results for lambda and beta. Temperature gradient -theta(')(0) is decreased by lambda and beta. Originality/value Here, the authors are interested to investigate rotating flow in a porous space. Dissipation and radiation effects are neglected. Effects of activation energy are studied. This work is not done yet in literature.
