Impact of Darcy–Forchheimer–Brinkman model on generalized Eyring–Powell liquid subject to Cattaneo–Christov double diffusion aspects

Abstract

In this study, influence of non-Fourier’s heat flux in 2D Darcy Forchheimer flow of modified Eyring–Powell for a stretching sheet is discussed. Here, thermal conductivity of modified Eyring–Powell model depends upon temperature and porosity variable as well as Cattaneo–Christov heat-mass flux effects are also considered. By means of some suitable similarity transformations and simple BCs, coupled PDEs are transformed into a set of coupled ODEs. Resulting ODEs are solved by using bvp4c technique. The graphical results are obtained via MATLAB. The pictorial outcomes of some physical parameters are displayed. The acquired outcomes disclosed that temperature gradient decreases with the growing values of thermal relaxation parameter Prandtl number, while the concentration profile decreases for higher Lewis number.
