| 总结: | The free convection boundary layer flow near a three-dimensional stagnation point region is studied numerically with the implementation of nanofluid. The effect of gravity modulation and heat generation or absorption are considered while constant wall temperature boundary condition in the nanofluid are applied in this study. The mathematical formulation derived based on Tiwari and Das nanofluid model undertake boundary layer and Boussinesq approximations is then transform into non-dimensional governing equation using similarity transformation technique. Keller-box method is used to solve the non-dimensional governing equations. The velocity and temperature profile as well as skin friction and Nusset number near the stagnation point are presented graphically and discussed briefly under the influence of gravity modulation, curvature ratio, heat generation parameter and nanoparticles volume fraction. The result obtained show that the effect of heat generation gives rise to the skin frictions and Nusset number while additional of copper nanoparticles increase the thermal conductivity of the fluid. |
