【摘要】 针对环境波高和船体垂荡运动对月池内流体运动的影响,采用CFD与模型试验相结合的方法,以某含月池的深拖母船为研究对象,数值模拟不同幅值规则波激励下月池内流体自由液面的爬升。结果显示,波浪幅值线性增加时,月池内流体液面的增加呈非线性。分析船体在波浪中的垂荡运动和船体静水中做不同频率垂荡简谐运动时的月池内流体运动,结果显示,船体垂荡运动存在明显双峰特性,且在船体垂荡运动频率为月池内流体共振频率时,月池内流体液面爬升最明显。更多还原

【Abstract】 Aiming at the influence of wave height and hull heave motion on the fluid motion in the moon pool,using a combination of CFD and model test, and taking the deep towed mother ship with moon pool as the research object, the fluid elevation in the moon pool under different amplitude regular wave excitation is numerically simulated. The results show that the increase in fluid level in the moon pool is nonlinear when the wave amplitude increases linearly. The heave motion of the hull in the waves and the fluid motion in moon pool when the ship is in simple harmonic motion of different frequencies in calm water are analyzed. The results show that the hull heave motion has obvious bimodal characteristics, and when the hull heave motion frequency is the fluid resonance frequency in the moon pool, the fluid level elevation in the moon pool is most obvious.更多还原
