Cavitation inception on ship ship propeller models

Cavities are volumes filled with vapor in a local low pressure region in a fluid flow . The beginning or inception of cavitation is important for scaling of cavitation . In this section the mechanism of cavitation inception is discussed and a simple theoretical model of bubble equilibrium is described. Arguments are given why diffusion and bubble dynamics can be neglected in cavitation inception . The parameters for scaling cavitation on ship propellers are given and the facilities used in this investigation are described.
