| 英文摘要 | This study conducts a comparative analysis of the drag reduction characteristics of radial and axial ventilation under various cruising speeds and ventilation flow conditions, exploring the differences in the drag reduction mechanisms between the two ventilation approaches. The results indicate that axial ventilation, by introducing axial gas momentum and providing effective suppression of pressure differential resistance, can achieve a significantly larger gas layer coverage area at relatively low ventilation volumes, thereby outperforming radial ventilation in terms of friction drag reduction. The drag reduction effect of axial ventilation is divided into three distinct regions: a moderate drag reduction rate region at low ventilation volumes, a low drag reduction rate region at moderate ventilation volumes, and a high drag reduction rate region at large ventilation volume. In contrast, radial ventilation exhibits two regions: a non-drag reduction region at low ventilation volumes and a drag reduction region at high ventilation volumes. The study suggests that for extended endurance, axial ventilation with a small ventilation volume should be prioritized, whereas radial ventilation with a large ventilation volume is more effective when seeking higher drag reduction rates. This research provides a theoretical basis for optimizing the ventilation drag reduction strategy under different operational conditions of underwater vehicles, contributing to more precise ventilation strategy formulation. |
