Impact of Injection on a Stagnation–point Flow of Copper Nanofluids over a Vertical Porous Shrinking or Stretchingplate in the Presence of Magnetic Field
نویسنده
چکیده
Nanofluids are the new generation way to enhance thermal properties of common fluids. The potential of nanofluidshave made them very useful in different heat transfer applications. In this paper, the injection velocity effects on copper nanofluids over permeable stretching/shrining surfaces are analysed in stagnation–point flow. Nanofluids are under the influence of magnetic field. The PDE governing the problem under consideration are transformed by similarity transformation into a system of ODE that is executed numerically using MAPLE 18 software. It is observed that the injection on magnetic field had greatly influenced the heat transfer characteristics in the copper nanofluid.
