Abstract: The numerical investigation of magnetohydrodynamic Falkner–Skan boundary layer flow of Cross nanofluid past a wedge in moving fluid is fundamental subject of current paper. The present work is the principal endowment in presenting the flow and heat transfer characteristics of Cross nanofluid past wedge geometry. Moreover, the consequence of heat generation/absorption and diffusion of chemically reactive species is also examined. Instead of conventional no-slip condition at the surface of wedge, Newtonian heat and mass conditions are utilized. The governing problem consisting of highly nonlinear coupled equations is numerically elucidated by the legendry shooting technique. The outcomes of analysis reveal that the wedge angle parameter resulted in boosting the fluids velocity while the temperature and concentration profiles exhibited decaying trend. Enrichment in fluid temperature and nanoparticle concentration fields is found by invoking the Newtonian heat and mass conditions. The increasing values of the heat generation or absorption parameter caused diminution of local Nusselt number. Additionally, an outstanding comparison with the results already reported in the literature is demonstrated for special case.
