摘要
激光测速作为一种先进的非接触式测量技术,在叶轮机械的研究中得到了越来越多的应用和发展。本文在总结上海交大叶轮机械实验室使用PDA和PIV系统经验的基础上,结合国内外新近的研究成果,介绍分析了激光测速技术的特点以使用中应注意的关键问题。
As an advanced un-intrusive flow measurement technology, the laser velocimeters have been widely employed to investigate the internal flow fields in Turbomachinery, in particular for the rotating flow fields. In this paper, two kinds of the typical laser velocimeters, the PIV system and LDA system were introduced. The key problems and solutions occurred in the applications were discussed in detail based on the published literature and the application experiences of Turbomachinery Laboratory of Shanghai Jiaotong University.
