The numerical and experimental research on unsteady cloud cavitating flow of 3D elliptical hydrofoil

摘要：

Using Singhals full cavitation model and a modified k–e RNG turbulence model, the unsteady cavitating flow and the dynamic shedding of cloud cavitation from the 3D elliptical foil were numerically investigated. For validating the simulation result, the corresponding experiments were carried out in cavitation tunnel at CSSRC. The modification of turbulence model made to the turbulence model addresses the influence of compressibility effect on turbulence by artificially modifying the turbulent viscosity and takes effect only in the compressible mixture flow region. The main features of cloud cavitating dynamics shedding agree well with the experimental observations.
