用激光多普勒流速仪(LDV)测量了血管狭窄段模型中的流动速度,考察了在不同来流雷诺数情况下流场的特性及模型的几何参数对流动的影响,得到了一些有益的数据和细节分明的流谱图。作为比较,还提供了用示踪法得到的各种模型的流场照片。二者有很好的一致性。
The flow velocity in the vascular stenosis model was measured by Laser Doppler Velocimetry (LDV). The flow field characteristics under different Reynolds number flows and the geometric parameters of the model were investigated. Some useful Data and detailed fluid chromatogram. As a comparison, photos of the flow field of various models obtained by the tracer method are also provided. The two have good consistency.
