DPIV技术及其在电厂取水流道物理模型试验中的应用

DPIV Technique and Its Application of Model Test of the Power Station Intake Runner

文中简要回顾了流动显示技术的发展过程,主要对数字粒子图像测速(DPIV)技术的原理、系统的组成及其在电厂取水流道物理模型试验流道流场测量中的应用作了详细介绍,并给出了流道流场的测试结果,指出DPIV技术将会在无接触流场测试中得到广泛应用。

In this paper, the technique of flow visualization has been introduced simply, the emphasis is in the principle of Digital Particle Image Velocimetry （DPIV）,the compose of DPIV system and its application of model test of the power station intake runner, and the experiment results of the flow field measurement are given, it point out that the technique of DPIV will get the extensive application in no touch flow field testing.
