Abstract
Wall-pressure fluctuations are of greatest interest in cavitating flows - a threshold phenomenon determined by pressure fields, which are an important source of the corresponding significant vibrations and loud noise in many practical applications. In this article, we measure the wall pressure fluctuations in attached compressible turbulent cavitating flows, and firstly report their statistical behaviors which are independent of cavity regimes.
