High Reynolds number wind tunnels are essential tools for testing theories of turbulence. This need has led to the construction of tunnels that use compressed gases as the working fluid, and such facilities have given new insights into the behavior of turbulence in wall-bounded flows. Here, we focus on results obtained at Princeton using the Superpipe and the High Reynolds number Testing Facility that have given us new insights on the behavior of wall-bounded flows, in particular, fully-developed pipe flow, and turbulent boundary layers in zero pressure gradients.

关于有边界流中雷诺数缩放的一些观察

雷诺数高的风洞是测试湍流理论的重要工具。这种需求导致了使用压缩气体作为工作流体的隧道的建设，而这种设施对围墙流动中的湍流行为有了新的认识。在这里，我们重点介绍使用超级管道和高雷诺数测试设施在普林斯顿获得的结果，这些结果为我们提供了关于边界流的行为的新见解，特别是充分发展的管道流以及零压力下的湍流边界层渐变。
