Abstract: The present work focused on two dimensional flow of an incompressible hybrid dusty fluid through a Darcy–Forchheimer medium over a stretched sheet. The Cattaneo–Christov heat flux model and the carbon nanotube properties are taken into an account. The problem is mathematically formulated from the flow, there after solved numerically with the help of RKF-45 method along with the maple package. Impacts of physical parameters of present problem such as, Eckert number, radiation parameter and Prandtl number are analyzed by means of graphs and tables with some notable applications. From the result we observed that, an escalating value of Pr diminishes the temperature profile for both fluids. Higher estimation of Kp reduces the velocity profile for both phases. Momentum boundary layer thickness decreases by increasing values of Fr. Furthermore, Heat transfer process is higher in dusty fluid when compare to hybrid nanofluid. And the higher radiation parameter plays a key role in cooling process.
