Numerical investigation of the hydroelastic response in cavitating flow around a flexible hydrofoil
IOP Conference Series: Materials Science and Engineering, 2015 The objective of this paper is to investigate the hydroelastic response of cavitating flows around a flexible hydrofoil. The numerical simulations are performed by solving the incompressible and unsteady Reynolds Average Navier-Stokes (URANS) equations via the commercial CFD software ANSYS CFX. The k-ω SST turbulence model with the turbulence viscosity

Study of the cavitating instability on a grooved Venturi profile [PDF]
, 2014 Instabilities of a partial cavity developed on a hydrofoil, a converging-diverging step, or in an interblade channel have already been investigated in many previous works. The aim of this study is to evaluate a passive control method of the sheet cavity.

The numerical study of the cavitation-structure interaction around 3D flexible hydrofoil
Journal of Physics: Conference Series, 2015 The closely coupled approach combined the Finite Volume Method (FVM) solver and the Finite Element Method (FEM) solver is applied to simulation the cavitation-structure interaction of a 3D cantilevered flexible hydrofoil in water tunnel. In the cavitating flow, the elastic hydrofoil would deform or vibrate in bending and twisting mode.
