Steady flow of a viscous, incompressible, electrically conducting, chemically reacting and heat radiating nano-fluid over a stretching sheet, with melting, in the presence of an applied transverse magnetic field considering viscous and joule dissipations into account is investigated. Using adequate similarity transformations, non-linear partial differential equations governing the problem are transformed into non-linear ordinary differential equations and then solved using bvp4c (Matlab’s boundary value problem solver). A comparison is done to validate the numerical results obtained in the present paper with the existing literature. Numerical results of velocity  temperature  and species concentration  are depicted graphically. Numerical values of skin friction coefficient  local Nusselt number  and local Sherwood number  are presented in tabular form. Such nano-fluid flows find applications in heat transfer processes, pharmaceutical processes, domestic refrigerators, heat exchanger, engine cooling, chiller, vehicle thermal management, etc.
