Abstract

The two constructions for measurement of cavitations threshold in fluid are presented. The elastic underwater jet's membranes as the model of uniflow and counter flow sensor are considered. The basic frequency of membrane’s auto vibration depending on characteristics of fluid and geo¬metric parameters of construction is calculated. The nu¬merical calculations and experimental re¬sults are compared.
