英文摘要This study systematically investigated the effects of the sweep angle on the cavitation dynamics of surfacepiercing hydrofoils using integrated experimental and numerical approaches. The key findings revealed that the sweep angle critically governed the cavity topology and shedding mechanisms. As the sweep angle increases, the cavity topology transitions progressively from crescent-shaped to triangular-pyramidal, and the cavity shedding modes evolve sequentially from "impact-type" cloud shedding to "open-type" cloud shedding, and finally to irregular small-scale shedding. These modes are accompanied by a reduction in the fluctuations of the unsteady load amplitudes, indicating a cavitation-suppressing effect induced by the sweep angle. The deflection angle of the re-entrant jet exhibits a negative relationship with the cavity closure line angle, which serves as the primary factor governing the cloud-shedding transition. At a sweep angle of 45 degrees, the cavitation mode shifted from sheet/cloud cavitation to leading-edge vortex cavitation, accompanied by the transformation of cloud shedding into irregular small-scale shedding. Concurrently, the near-cavity flow was restructured from chordwise-dominated patterns to strongly three-dimensional vortical patterns. Spectral energy analysis revealed that increasing sweep angles redistributed the turbulent kinetic energy from large-scale coherent structures to small-scale dissipative eddies, signifying a paradigm shift from inertial energy cascades to viscous dissipation dominance.
