摘　　要：介绍了二维粒子图像测速技术(2DPIV)的原理和使用中应注意两个关键问题,并实际测量了某模型通风房间的流场,与数值模拟结果进行了比较,结果表明PIV可以和CFD结果相互验证。PIV还可以提供传统测量工具无法提供的流场信息。The working principles of Two Dimensional Particle Image Velocimetry （2DPIV） were presented and several key problems were pointed out. The flow field of a model room were measured by PIV and simulated by CFD respectively. It＇s shown that PIV can be employed as a practical tool to validate CFD simulation result. PIV also can supply some flow information that traditional measurement tools can＇t supply.

关 键 词：粒子图像测速技术(PIV) 通风 数值模拟
