粒子图像测速（PIV）测量的目的是提供实验数据的SimInhale基准的情况下，在这项工作中。因此，我们提出了一个折射率匹配的，透明的基准几何模型，其中的速度和湍流动能场进行检查，在空气中的流速可比15，30和60 L/min（Re近似1000-4500）。此外，这些结果与大涡模拟（LES）进行了比较。结果表明，雷诺数的定性速度场的范围内，这项工作所涵盖的独立。PIV和LES数据之间的良好的协议，与轻微的过度预测的湍流动能的模拟。所获得的实验数据将与最近发表的其他结果一起成为一个公共的、可公开访问的ERCOFTAC数据库的一部分。
Particle Image Velocimetry (PIV) measurements with the aim of providing experimental data for the SimInhale benchmark case are presented within this work. We, therefore, present a refractive index matched, transparent model of the benchmark geometry, in which the velocity and turbulent kinetic energy fields are examined at flow rates comparable to 15, 30 and 60 L/min (Re approximate to 1000-4500) in air. Furthermore, these results are compared with Large Eddy Simulations (LES). The results reveal a Reynolds number independence of the qualitative velocity field in the range covered within this work. Good agreement is found between the PIV and LES data, with a slight over-prediction of turbulent kinetic energies by the simulations. The obtained experimental data will be part of a common, publicly accessible ERCOFTAC database along with additional results published recently.
