| 摘 要： | 对后倾角35°类车体在模型风洞中进行实验，运用三维热线风速仪在选定测点上对空间三个速度分量进行采样。对采得的瞬时值进行平均值处理，并制成相应的云图和矢量图。由图谱说明：类车体尾迹区流动具有对称特性，以一对拖曳涡为其主要特征，并明确了拖曳涡的涡核位置。

| Abstract: | The Ahmed model with 35° slant angle has been tested in the model wind tunnel. The components of velocity have been captured by using 3D CTA. By dealing with the transient value of velocity, the contour and vector spectrums are presented. According to the spectrums, the symmetry feature of the flow structure is showed with drag vortex pair and the location of the core of the vortex is ascertained. |
