摘　　要：Thermodiffusion effects on stagnation point flow of a nanofuid towards a stretching surface with applied magnetic field is presented.Similarity transforms are applied to reduce the equations that govem the flow to a system of nonlinear ordinary differential equations.Runge-K utta-Fehlberg method is applied to solve the sy stem.Results are compared with existing solutions that are special cases to our problem.Concrete graphical analysis is carried out to study the effects of different emerging parameters such as stretching ratio A,mag netic infuence parameter M,Prandtl number Pr,Lewis number Le,Brownian motion parameter Nb,thermophoresis parameter Nr,nanofluid Lewis number Ln,modified Dufour parameter Nd and Dufour solutal number Ld coupled with comprehensive discussions.Numerical effects of local Nusselt number,local Sherwood number and nanofluid Sherwood number are also discussed.
