摘要
笔者在北京航空航天大学流体力学研究所多年从事系统的PIV测试技术研究,经过科研攻关成功研制出目前国内第一套完善的实时数字式粒子图像测速(DigitalParticleImageVelocimetry)系统,实现了速度场和涡量场的实时测量,而且已经成功地应用于各项流体力学的实验测量中,其中包括:1.5M超声速喷流实验、三角翼前缘涡破裂复杂流场测量实验、大型工程水洞流场校测、绕摆动圆柱卡门涡测量实验以及锥阀管道模型和漩涡分离器内部流场测量实验等[1～3]。
The Particle Image Velocimetry (PIV) played an important role as the development of measurement techniques in fluid experiments. We specialized in designing the first set of Digital PIV system compatible with the foreign products, and it had been successfully applied in several kind of fluid experiments, such as: 1.5M Laval jet flow measurement, delta wing vortex breakdown measurement, velocity uniformity calibration for industry fluid tunnel, Karman vortex measurement around vibrated cylinder, and valve fluid or vortex separator inner fluid measurements[1][2][3].
