摘要
本文将一台TSI 9100-7型两分量激光测速仪改进为可测三个速度分量的LDV系统,并用于测量风洞中椭球体模型、双三角翼模型大迎角下的复杂流场三维速度分量。流场横截面内的速度矢量分布与相同实验条件下的流态显示结果相符合,并对涡流场加以分析。
The paper reports that a two-component TSI 9100-7 LDV system was developed into the LDV enable to measure three component velocity and that with the developed LDV the complex vortex flow field of a prolate spheroid and a double-delta wing at high angle of attack in the wind tunnel was measured. The test wind velocity was 20 m/s. The obtained velocity vector distribution in the measured plane coincided with the flow visualization results under the same test condition. In addition these vortex flow field was analysed.
