摘　　要：粒子图象测速技术（ParticleImageVelocimetry）是当今国际上流体力学领域正在发展中的一门新的测试技术。本文介绍了利用CSSRC建成的PIV系统在小循环水槽中进行叶栅绕流流态显示及流场测量的试验。文中给出一些典型的叶栅绕流的粒子图象和通过自相关法计算得到的速度矢量图。结果表明，CSSRC的PIV系统已能用于流场的显示和测量；并不失为一种流动测量的先进工具。Particle Image Velocimetry (PIV) for measuring the flow field is a developing techniqUe in the field of fluid mechanics. This paper describes an experiment to measure quantitatively and visually the flow around a plate cascade using PIV in a circulating water channel in CSSRC. Some typical flow images and vector maps are shown. The results indicate that the PIV system developed in CSSRC can be used to measure and visualize the flow field and the PIV system is a better tool to visualize the flow field.
