Abstract

This paper provides a compendium of the numerical model that goes under the name of FloodW. This code is a fast tool for the simulation and the analysis of the effects of flooding water on ship dynamics and loads in time domain, developed for safety purposes. It has been recently involved in the international benchmark study on simulation of flooding and motions of damaged Ropax vessels within the EU Horizon 2020 project FLARE, where the name FloodW was given for the first time. Indeed, the development of the code started almost 10 years ago for still water applications, limited to ship motions, up to flooding simulation in regular waves with the possibility to study also non-linear hull girder loads. The core feature of the flooding water modeling is in the assumption of a free surface normal to the apparent gravity vector, which is evaluated accounting for ship and water dynamics. Although this approach, from validations with experimental data, was found accurate in the whole range of filling levels of the damaged compartment, with finer accuracy for intermediate fillings, an alternative method was also proposed and implemented, pertinent to low filling levels. Therefore, this paper provides a comprehensive description of the FloodW code together with its applications, including also the recent developments in participating to the benchmark FLARE, regarding ship flooding in irregular wave scenario.

全面介绍并应用 FloodW 仿真代码解决船舶淹没问题：从静水到不规则波浪情景

本文简要介绍了以 FloodW 命名的数值模型。该代码是一种快速工具，用于模拟和分析洪水在时域中对船舶动力学和载荷的影响，是为安全目的而开发的。最近，它参与了欧盟地平线 2020 项目 FLARE 中的受损 Ropax 船舶洪水和运动模拟国际基准研究，并首次被命名为 FloodW。事实上，该代码的开发始于近 10 年前的静水应用，仅限于船舶运动，直至规则波浪中的洪水模拟，同时还可以研究非线性船体大梁载荷。洪水模型的核心特征是假定视重力矢量的自由表面法线，并根据船舶和水的动态进行评估。根据实验数据的验证，这种方法在受损船舱的整个填充水平范围内都很精确，中间填充的精确度更高，但同时也提出并实施了一种替代方法，适用于低填充水平。因此，本文全面介绍了 FloodW 代码及其应用，包括参与基准 FLARE 在不规则波浪情况下船舶淹没方面的最新进展。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
