摘要
以3艘海洋科考船为研究对象,采用CFD软件模拟不同艏部线型在经济航速和最大航速下艏部兴波波形和自由液面气泡沿船体曲面下泄轨迹。计算结果表明,球鼻艏线型可明显降低船首兴波波峰高度;安装导流罩可以解决船底宽度不满足多波束设备宽度的问题,但同时会增加船舶阻力并产生紊流;采用一体化隐式球艏线型有较好的兴波阻力性能同时兼顾较强的防气泡能力。
Taking three marine scientific research ships as the research objects,CFD software is used to simulate the bow wave making waveforms and free surface bubbles along the hull curved surface of the ship with different bow line types at economic speed and maximum speed.The simulation results show that the bow can evidently reduce fore-body wave height.Installing fairing can solve the problem that the flat width of ship does not meet the size of multi-beam echo sounder,but it will generate additional resistance and turbulence.The integrated implicit bow has great performance of wave resistance as well as anti-bubble ability.
