Abstract
This article deals with Darcy-Forchheimer viscous liquid flow by an exponentially stretching curved surface. Flow in permeable space is specified via Darcy-Forchheimer relation. Cattaneo-Christov mass and heat diffusion relations are considered in the mathematical formulation. Appropriate variables lead to highly non-linear ordinary differential equations. The obtained problem is solved numerically through ND Solve technique. The outcomes of different sundry variables on velocity, temperature and concentration are sketched and discussed. The physical quantities like skin friction and heat and mass transfer rates are examined graphically. Our results indicate that the heat and mass transfer rates are enhanced for larger values of thermal and concentration relaxation parameters respectively. (C) 2020 Elsevier B.V. All rights reserved.
