摘      要：The melting phenomenon in two-dimensional(2 D)flow of fourth-grade material over a stretching surface is *** flow is created via a stretching surface.A Darcy-Forchheimer(D-F)porous medium is considered in the flow *** heat transport is examined with the existence of the Cattaneo-Christov(C-C)heat *** fourth-grade material is electrically conducting subject to an applied magnetic *** governing partial differential equations(PDEs)are reduced into ordinary differential equations(ODEs)by appropriate *** solutions are constructed analytically through the optimal homotopy analysis method(OHAM).The fluid velocity,temperature,and skin friction are examined under the effects of various involved *** fluid velocity increases with higher material parameters and velocity ratio parameter while decreases with higher magnetic parameter,porosity parameter,and Forchheimer *** fluid temperature is reduced with higher melting parameter while boosts against higher Prandtl number,magnetic parameter,and thermal relaxation ***,the skin friction coefficient decreases against higher melting and velocity ratio parameters while increases against higher material parameters,thermal relaxation parameter,and Forchheimer number.
