Numerical Simulation of Interaction between Fluid and Vapor Structures in Multiphase Flow around Hydrofoil.
Original language description
This work deals with the numerical simulation of interaction of fluid and vapor structures on NACA 2412 hydrofoil during the partial cavitation oscillation. This interaction is supposed to be the most important reason for the cavity shedding. The hydrofoil with the span/chord ratio of 1.25 corresponds to the experiments carried out in the cavitation tunnel. The Detached Eddy Simulation is used on full 3D geometry of the straight NACA 2412 hydrofoil to capture the strong influence of side-wall effects. Real properties of water including estimated content of undissolved air are considered to affect the compressibility of the mixture and its speed of sound. The link between strong pressure pulses during the cavity cycles and the interaction of fluid and vapor structures is discussed in detail.
