摘要
归纳了几种典型的流场测速技术测速原理、优缺点及应用研究进展,其中基于图像处理技术的新型测速技术有PIV、LDV、PDPA等。对比分析可知,多种基于各种测量原理的测速技术都可用,但每种测速技术无法达到各测量中理想的要求,在功能或适用流场上总会有弊端,流场测速时需要有效结合两种或多种方法,选定适合所测流场的测速技术才能进行高效率测量。最后对PIV、LDV今后的发展方向进行了展望。
The paper concluded the principle, advantages and disadvantages, application research progress of several typical flow field velocimetry technologies. New-type velocimetry technology based on image processing technology involved PIV, LDV and PDPA etc. Contrast and analysis results showed various velocimetry technology based on various measurement principles could be used, while each velocimetry technology failed to reach ideal requirements of all measurement, always possessed disadvantages in function and applied flow field. Thus, in order to obtain efficient flow field velocimetry, effective combination of two or more methods and the velocimetry technology suitable for the flow field to be measured were needed. At last, the future development direction of PIV and LDV were prospected.
