Sheet cavitation and cloud cavitation, re-entrant jet and three-dimensionality Article uri icon

abstract

  • The unsteady behaviour of a sheet cavity on a hydrofoil under stationary conditions is important with respect to both noise generation and erosion. Observations of two-dimensional as well as three-dimensional cavities are performed. From the observation it is concluded that the formation of a re-entrant jet is of major importance to explain the unsteadiness. Numerical simulation of the two-dimensional cavitating flow is performed, showing good agreement with the observations.
