| Summary: | A theoretical study on free convection boundary layer nanofluid flow near a three-dimensional stagnation point body was conducted under microgravity environment subjected to heat flux boundary condition. g-Jitter effect occurs under microgravity environment caused a fluctuation gravitational field on the fluid system consist of copper nanoparticle and water base fluid. The flow problem was governed into a system of partial differential equation and solved numerically using implicit finite different scheme. The result was presented graphically in term of skin friction coefficient and Nusselt number. The results show that curvature ratio parameter that represent the geometrical shape of boundary body produced different types of stagnation point flow cases. In addition, the increases of amplitude modulation parameter values increase the fluctuation amplitude of each skin friction coefficients and Nusselt number while contradict behavior were noticed as frequency of oscillation parameter increased. Besides that, increases of nanoparticle volume fraction increase both skin friction coefficients and Nusselt number. |
