用数字全息测速仪对湍流管流中的速度场进行了三维同步测量。我们提出了两束激光的全息技术。在这项研究中，雷诺数设定为15000。通过将实验方法的结果与Satake等人的DNS数据进行比较，证实了实验方法的准确性。[4]当使用相同的雷诺数时。结果表明，该方法得到的速度分布与数值模拟结果吻合较好。
Three-dimensional simultaneous measurements of velocity field in a turbulent pipe flow are performed by digital holographic velocimetry. We proposed holography technique with two laser beams. For this study, the Reynolds numbers was set to be 15000. The accuracy of the experimental method was confirmed by comparing the results from the method with DNS data by Satake et al. [4] when using the same Reynolds number. The velocity profiles obtained from the method was found to be in good agreement with that of the DNS data.
