The analysis is made to explore the Darcy-Forchheimer flow and heat transfer of Maxwell fluid over a vertical stretching sheetuniform heat source/sink. Using similar transformations, the governing partial differential equations (PDEs) are converted intonon-linear ordinary differential equations (ODEs). The resulting ODEs are solved numerically by Runge-Kutta fourth order method along with shooting technique. The outcomes of relevant parameters on velocity, temperature as well as skin friction coefficient and local Nusselt number are illustrated through graphs and tables. It is found that local inertia parameter, which is responsible for inertia drag, reduces the fluid velocity but adverse effect is observed on temperature field.
