Abstract

It is shown that the velocity fluctuation spectra measured using a hot wire in the potential flow region of the near field of a turbulent jet with a coflow can be converted into pressure fluctuation spectra. The proposed conversion method is based on the fact that the structure of instability waves, which make a decisive contribution to jet near-field fluctuations, resembles homogeneous one-dimensional waves, which makes it possible to locally link pressure fluctuations and the fluctuations of the streamwise velocity component measured by a hot wire.

基于热线的同流情况下喷气近场压力波动估计

摘要研究表明，在带有共流的湍流射流近场的势流区域使用热线测量的速度波动谱可以转换为压力波动谱。所提出的转换方法基于这样一个事实，即对射流近场波动起决定性作用的不稳定波的结构类似于均匀的一维波，这使得将压力波动和用热线测量的流向速度分量的波动局部联系起来成为可能。
