MHD Forced Convection Nanofluid Flow Over a Stretching Surface with Suction or Injection Effects

In this study we analyzed the influence of thermal radiation, magneticfield and chemical reaction on the forced convection flow of Cu-water nanofluid in presence of non-uniform heat source/sink and suction/injection effects. The governing partial differential equations are transformed into system of nonlinear ordinary differential equations by using self similarity transformation and then solved numerically using bvp5c Matlab package. Dual solutions are presented for suction and injection cases. We found an excellent agreement of the present results with the existed studies. The effects of non-dimensional governing parameters on the flow, temperature and concentration profiles are discussed and presented through graphs. Also, numerical results for skin friction coefficient and local Nusselt and Sherwood numbers are presented. Results indicate that dual solutions exist only for certain range of suction/injection parameter and increasing in the value of magneticfield parameter depreciates the friction factor along with the heat and mass transfer rate.
