摘　　要：为了研究含静态混合元件炉管中流体边界层被破坏的行为规律 ,设计了 2种实验系统和测量方法。对模拟状态下流体的速度场进行测量与显示 ,所获得的结果可用于直观比较 ,也可为数值研究和工业应用提供可信度高的参照依据。由流体实验得出结论 :(1)静态混合元件对流体的扰动可用 7孔探针测量方法测量 ,测量结果可用于直观比较和定性分析 ;(2 )PIV方法也可用于静态混合元件扰动流场的测量 ,但受圆形管子光折射率的限制 ,用于管外近距离处测量 ,可获得管截面的速度分布。In order to study the destroy law of the fluid boundary layer in the furnace tubes with static mixer unit, two experimental system are designed and relevant measuring methods are presented. The velocity field of the fluid is simulated, measured and visualized. The results obtained in the experiment are treated as a highly reliable comparision to both the computational value and the practical values. Conclusions are drawn from the experiment as follows: (1) the fluid field can be measured with a seven-hole probe, and the results measured can be used for intuitionistic comparison and qualitative analysis; (2) PIV (particle image velocimetry) method can also be used for the measurement of flow fluid disturbed by the static mixer.
