| Abstract: | 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. |
