定性地描述了螺旋桨叶尖涡空泡的概念，从而区分了
尾涡、局部叶尖涡和前缘涡。Inception行为的改进
使用这种区别。对发展的叶尖涡空泡的观察表明，

A concept of tip vortex cavitation on propellers is described qualitatively, leading to the distinction of
trailing vortices, local tip vortices and leading edge vortices. Improvements of the inception behaviour
using this distinction are presented. Observations on developed tip vortex cavitation are given to show
that the concept of vortex bursting seems inadequate. The problem of "broadband" vibrations due to a
cavitating tip vortex is illustrated. Arguments are given for the fact that a three dimensional approach
is necessary to describe shedding of cloud cavitation at the trailing edge of a sheet cavity.
