To investigate viscous flows around low-aspect-ratio wings of a micro-aerial vehicle(MAV) at low Reynolds numbers,experiments are conducted in a wind tunnel using particle image velocimetry(PIV) and a smoke wire technique.

应用粒子图像速度场仪(PIV)和烟线两种流动显示技术,测量低雷诺数下小展弦比机翼粘性绕流的流场。

The flow field of two opposed jets was experimentally investigated with the smoke-wire technique and hot-wire anemometer for the stability of impingement plane and stagnation point offset at various nozzle separations and exit velocity ratios.

运用烟线法和热线风速仪对两喷嘴撞击流流场进行了实验研究,考察了不同喷嘴间距、不同气速比下撞击面的稳定性和撞击面驻点的偏移规律。
