| 英文摘要 | This study systematically investigates the natural ventilation characteristics around surface-piercing hydrofoils using an integrated experimental and numerical methodology, focusing on the modulation mechanisms of the sweep angle (Lambda). A comprehensive flow-regime classification is developed for moderate-to-high depth-based Froude numbers (Fr-h), and three distinct states are identified: tip-vortex-induced ventilation (TVIV), fully wetted flow (FW), and nose ventilation (NV). The stability domains and transition thresholds are quantitatively mapped within the Lambda-Fr-h parameter space. The critical findings demonstrate that the TVIV-to-FW transition is governed by spanwise secondary flow-induced nonlinear vortex interactions. Multiscale vortex fusion drives the intermittent breakdown of secondary tip vortices, forming a tip-locking phenomenon that suppresses TVIV development. This is quantitatively validated through analysis of the circulation distribution and spectral coherence characteristics. Synergistic interactions between attenuated leading-edge adverse pressure gradients and the failure of free-surface sealing trigger the FW-to-NV transition, accompanied by the disappearance of the choking effect. Significantly, the stable FW regime delivers superior hydrodynamic performance across a broad velocity range at moderate values of Lambda. Temporal evolution analysis indicates that TVIV takes an order of magnitude longer than NV at identical Fr-h with both timescales being inversely proportional to Fr-h. These findings provide critical insights for anti-ventilation design in high-performance marine applications. |
