| Résumé : | In order to investigate the erosion extent and mode of cavitation in different states by the commercial code FLUENT and evaluate the reliability of the software, the collapse processes of a vapor bubble, which was near or on the wall under the conditions in the stationary water or the high speed water, were simulated by the numerical calculation by using a 2D model. The results are in accordance with results presented by other researchers, so the simulation may testify to the validation of the code. We suppose that a bevel jet, which is generated contrary to the flow direction when the bubble collapses in high speed flow, may cause the ripple and fish-scale pit damage found on the transition parts of many hydraulic systems. |
