Abstract This communication addresses the Darcy-Forchheimer flow by an unsteady curved stretching surface. Flow in porous medium is characterized by Darcy-Forchheimer relation. Cattaneo-Christov double diffusion expressions are implemented in modelling. Suitable transformations correspond to a strong nonlinear ordinary differential problems. The problems are numerically solved. Outcomes of emerging flow variables on velocity, temperature and concentration fields are plotted. Skin friction coefficient and local Nusselt and Sherwood numbers are computed and examined. Our findings reveal that the skin friction coefficient is an increasing function of Forchheimer number.
