| Abstract: | The main principle of the WENO scheme is described and a multi-block numerical algorithm for 3D flowfield is developed based on the WENO scheme. The external flowfield of a hemisphere-cylinder and anvogival body with six flat fins are simulated with this algrithm. The computational results for characteristics of the flowfield around these bodies and aerodynamic forces acting on these bodies are presented, and are compared eith experimental data. It is shown that the WENO scheme is robust indeed. |
