Here we discuss hydromagnetic flow of Darcy Forchheimer flow of nanomaterial over a stretched sheet. Dissipation, radiation and Joule heating are considered. Significant characteristics of random motion and thermophoresis effects are discussed. Additionally Soret and Dufour behaviors are examined. Entropy generation is discussed. Binary chemical reaction is scrutinized. Solutal and thermal stratifications are also discussed. Bejan number is calculated. Nonlinear ordinary differential expression is obtained through appropriate transformations. Resulting system are solved through ND-solve method. Influence of flow variables on velocity, temperature, concentration, entropy rate and Bejan number are examined. Performance of skin friction, heat transfer rate and Sherwood number are graphically examined. An enhancement in electric field variable improves the velocity. Higher mixed convection variable corresponds to augment velocity. An augmentation in temperature is seen for magnetic and radiation variables. Temperature has similar effect for random and thermophoresis diffusion variables. Concentration holds reverse effect for Soret and Lewis number. An increment in entropy rate is noted for radiation and magnetic variables. Larger electric field variable reduces the entropy generation.
