摘要:
首先对目前的PIV(ParticleImagingVelocimetry)技术进行了总结 ,针对该系统设备复杂、价格昂贵的现实 ,提出了一种利用对单次曝光的流场空间域激光层析图像进行两次傅立叶变换后获得的频域图像求得最大互相关系数的二维速度场测量的新思路 .实验表明 :利用该方案有可能开发出针对小速度测量范围的实用粒子图像测速仪 .
Abstract:
The char acteristics of different PIV ( Particle Imaging Velocimetry) technologies ware gener alized in this paper. In v iew of the complexity and hig h ex pense of these systems, a new approach to obtain the 2- D velocity field based on the tw in FFT to the single spatial laser tomo graphy images is proposed and a simple system based on this method is also dev eloped. The ex perimental results show that g ood effect was achieved for the measur ing range of low velocity and the PIV wit h lower expense can be ex pected.
