The current article describes the influence of thermal radiation and heat transfer on magnetohydrodynamic Darcy-Forchheimer flow of Prandtl nanofluid over a stretching surface. The mass flux and thermal transmission conditions of zero nanoparticles are entrenched at the boundary. The similarity transformations have been applied on the flow governing equations, so they reduced to nonlinear coupled ordinary differential equations. The resultant equations which restrain the flow are then solved numerically by using Runge-Kutta fourth- order method along with shooting technique. The impacts of various physical parameters such as magnetic field parameter, fluid parameter, radiation parameter, Prandtl number, thermophoresis parameter, Brownian motion parameter, Lewis number, etc. on the velocity, temperature and nanoparticle volume fraction profiles have been examined and discussed elaborately through graphical illustrations. The influence of physical parameters on local skin-friction coefficient, and the rate of heat transfer are computed and analysed in tabular form. Skin-friction coefficients are affirmed as increasing functions of porosity and Forchheimer parameters.
