Abstract

The synergistic failure mechanism induced by cavitation and solid particle erosion poses a significant challenge to the durability of fluid machinery components operating under high-pressure, multiphase flow conditions. This study investigates this synergistic phenomenon through a case study of a needle valve within a heavy fuel oil injector. A comprehensive numerical approach, integrating the SST κ-ω turbulence model, the Mixture multiphase model, and the Discrete Phase Model (DPM), was employed to analyze the transient interaction between phase change and particulate erosion during the valve opening process. The results identify the small-lift stage (lift
