Cavitation and particle erosion are critical factors affecting the performance and durability of hydraulic machinery. This study employs a combined numerical simulation approach by integrating a cavitation model with a Discrete Phase Model(DPM) erosion model. It examines single erosion and cavitation-erosion synergy under varying cavitation inducer angles. The results show that intensified vorticity behind the inducer increases particle concentration and sliding erosion, leading to higher erosion rates and larger erosion areas compared to the single erosion model. Additionally, a direct correlation is established between cavitation occurrences, particle velocity, vorticity, and erosion rates at different rotational speeds. Comparative analysis with experimental data indicates an 11.52% improvement in predictive accuracy for wear using the cavitation-erosion synergy model. These findings provide valuable insights for predicting wear in hydraulic machinery under cavitation and particle erosion conditions, contributing to enhanced equipment reliability and extended service life.
