Cavitating flow simulation with mesh development using Salome open source software

Abstract:

Cavitating flow simulation is very helpful for understanding the mechanism of cavitation in turbomachinery. However, the simulation accuracy may depend on the quality of mesh generation for computational domain source software Salome. The unsteady cavitating flow around a hydrofoil NACA 0015 is solved based on OpenFOAM, the results show that grid/mesh has important effects on the cavitating flow characteristics such as cavity revolution, vortex shedding. The comparison of cavitation flows among different mesh generation methods is conducted and it is noted that the cavitating flow with the structured mesh and well controlled node distribution can reproduce experimental results fairly well. Furthermore, mesh development using Salome greatly reduces calculation time of the flows simulation.
