Abstract:
Based on FLUENT6.3, the turbulent model of standard k-ε and equilibrium wall function with boundary layer mesh which was used to solve the flow in the near regions was chosen to research the tri-component force coefficient of streamline-liked section when Reynolds number is 1.38×106. The numerical simulation results were compared with the data obtained from wind tunnel test at high Reynolds number. Meshes which can be identificated preferably were used to solve the tri-component force coefficient under different Reynolds number conditions. The results show that the tri-component force coefficient of streamline-liked section can be identificated preferably by using reasonable control of mesh which is in the near regions when Reynolds number is more than 6.0×105. However, the numerical simulation results calculated by FLUENT6.3 isn't ideal when Reynolds number is less than 6.0×105.
