Abstract

The paper dwells on the physical assumptions and the mathematical description of the model of the bubble cavitation inception in the flow around a hydrofoil. The objective of the model is to anticipate the risk of the cavitation inception when the flow around the hydrofoil is turbulent. The methods of the stochastic processes theory have been applied in order to determine the time evolution of the bubble radius probability distribution. The numerical application of the model is discussed. The methodology of combined experimental and theoretical research of the bubble cavitation inception in the flow around the arbitrary hydrofoil is proposed. 1 Introduction Unsteady cavitation is extremely dangerous for the operating fluid-flow facilities,
