Modelling of Cavitation with RANSE CFD
By Keun Woo Shin, PhD student at the Technical University of Denmark, Department of Mechanical Engineering.
Although cavitation is mostly an undesirable occurrence in high-speed liquid flows of various engineering devices like ship propellers, pumps, hydraulic systems etc, due to such negative effects as noise, vibration, erosion and performance degradation, the demand of industry for heavier loads makes it unavoidable. As computational fluid dynamics becomes common, the capability for numerical simulation of cavitating flows is of critical importance for efficient design of high-performance engineering devices. To develop a reliable numerical model, several cavitation models are implemented in EllipSys, an incompressible Reynolds-averaged Navier-Stokes (RANS) solver, which is developed in cooperation of the Department of Mechanical Engineering at DTU and the Department of Wind Energy at RISØ.
