Minimal cavitation number and cavity width in plane and axisymmetric channels

  • L. A. Epshtein
Article

Abstract

This paper presents a study of cavity width behind a body in two-dimensional and axisymmetric channels. Equations are given for calculating the minimal cavitation number and also for calculating the dependence of the cavity width on the cavitation number and on the ratio of the transverse dimensions of the body and the channel.
