| Abstract: | The FSI (fluid-structure interface) effect was considered in the wind tunnel test and numerical simulation for improved Ahmed body. The validity of numerical simulation method about FSI was confirmed with body displacement data which measured by scaled wind tunnel test. By experimental and numerical methods, the change regulation of aerodynamic force and moment was described when FSI was considered and the internal mechanism of the change of aerodynamic force and moment was revealed. It is concluded that the FSI effect should be considered in vehicle design. |
