| 1 | Implicit large eddy simulation of unsteady cloud cavitation around a plane-convex hydrofoil显示文摘The present paper focuses on the erosive cavitation behavior around a plane convex hydrofoil. The Zwart-Gerber-Belamri cavitation model is implemented in a library form to be used with the OpenFOAM. The implicit large eddy simulation(ILES) is applied to analyze the three-dimensional unsteady cavitating flow around a plane convex hydrofoil. The numerical results in the cases under the hydrodynamic conditions, which were experimentally tested at the high speed cavitation tunnel of the école Polytechnique Fédérale de Lausanne(EPFL), clearly show the sheet cavitation development, the shedding and the collapse of vapor clouds. It is noted that the cavitation evolutions including the maximum vapor length, the detachment and the oscillation frequency, are captured fairly well. Furthermore, the pressure pulses due to the cavitation development as well as the complex vortex structures are reasonably well predicted. Consequently, it may be concluded that the present numerical method can be used to investigate the unsteady cavitation around hydrofoils with a satisfactory accuracy. | HIDALGO Victor 罗先武 ESCALER Xavier 季斌 AGUINAGA Alvaro | 2015 | Journal of Hydrodynamics2015，27，6： | 5 |
| 2 | Numerical study of unsteady cavitation on 2D NACA0015 hydrofoil using free/open source software显示文摘The free/open source software as OpenFOAM,Salome meshing and python language under Debian Linux system are evaluated to model unsteady cavitating turbulent flow around a NACA0015 hydrofoil. Based on the cavitation model proposed by Kunz and large eddy simulation(LES) method, we denote the benefits of free software and open source tools as an alternative to proprietary software of computational fluid mechanics, and provided a modified cavitation model to improve numerical accuracy.The simulation results of typical break-off cycle for cavitation shedding are compared to available experimental data, and validated using image processing to find percentage of similarities. The sheet cavity frequency of 7.752 Hz was obtained based on cavitation evolution and pressure fluctuations. The study gives relevant information for CFD software development in the future. | Victor Hidalgo Xianwu Luo Bin Ji Alvaro Aguinaga | 2014 | Chinese Science Bulletin2014，59，26： | 2 |
