Some Features of Water Flows With Ventilated Cavities

Abstract

A survey of the main mechanisms of air entrainment in largely developed cavity flow is given, with paticular attention being given to plane, almost horizontal flows. Specific characteristics of dimensional analysis in this case are exhibited. The evolution of flow configuration when the airflow rate changes is described. Special emphasis is placed on cavity pulsation and its physical characteristics. Some aspects of the pulsation mechanisms are discussed, from a qualitative point of view, with a more detailed examination of the phase relations between the quantities involved.
