摘要

本文系统地研究了风侧船和背风侧船并排布置时，风侧船对风侧船的屏蔽现象。新引入屏蔽效率参数来衡量水平距离、垂直距离和波角三个关键参数的屏蔽效果。引入理论波幅（TWA）和有效波幅（EWA）两个新概念，阐明了屏蔽效应的物理机理。分析包括一系列的场景来研究每个参数对滚转、摇摆和升沉运动的影响。对比研究了自由条件和固定条件下的迎风侧船舶，分析了船舶边界条件对屏蔽效果的影响。数值结果表明，这三个参数对屏蔽效果有显著影响，且在不同的运动响应中，各参数的作用有所不同。固定条件下的屏蔽效应比自由条件下更明显。

Numerical investigation for shielding effects of two vessels in side-by-side configurations

This study systematically investigates the shielding phenomenon that the weather-side vessel imposed on and lee-side vessel when the two vessels are positioned in side-by-side configurations. Shielding efficiency parameter is newly introduced to measure the shielding effects of three key parameters: horizontal distance, vertical distance, and wave angle. Two new concept, Theoretical wave amplitude (TWA) and Effective wave amplitude (EWA), are introduced to elucidate the physical mechanism of the shielding effect. The analysis includes a range of scenarios to study the effects of each parameter on roll, sway, and heave motions. The weather-side vessel with both free and fixed conditions is comparatively investigated to analyze the effects of vessel boundary condition on the shielding effect. Numerical results demonstrate that the three parameters significantly impact the shielding effects and the role of each parameter varies for different motion responses. The shielding effect is more pronounced for fixed condition than free case.
