摘要

专利船体叶片,节能附件,用于减少船舶的动力需求。它是一种横向固定在船尾的水翼。由于船体尾部的加速流动,在船体叶片的吸力侧出现了一个有助于减少船尾波浪的负压区。本研究通过计算流体动力学(CFD)模拟,在模型尺度上详细研究了船体叶片对船舶阻力分量的影响。OpenFOAM(开源现场操作和操作)已被用作流动求解器,它能够解决不同类型的流体动力学问题。在数值研究的范围内,改变了船体叶片的弦长,以考察其对总阻力的影响。研究结果显示,该船的总阻力显著降低了22.9%。

An investigation into the effect of the Hull Vane on the ship resistance in OpenFOAM
The patented Hull Vane, the energy saving appendage, is used to reduce the power need of the ships. It is a hydrofoil wing transversely fixed at the transom bottom of the ships. A negative pressure zone, which helps to reduce the stern wave, appears on the suction side of the Hull Vane due to the accelerated flow from the aft of the hull. In this study, the effect of the Hull Vane on the resistance components of the ship has been investigated in detail on the model scale by performing computational fluid dynamics (CFD) simulations. OpenFOAM (Open source Field Operation and Manipulation) has been used as a flow solver which is able to solve different types of fluid dynamics problems. In the scope of the numerical study the chord length of the Hull Vane has been changed to examine its effect on the total resistance. A significant 22.9% reduction on the total resistance has been observed on the subject ship as the result of the study.
