摘要

摘要:准确预测船舶在陡峭规则波浪或天然航道中的行为必须考虑非线性波浪响应,特别是横摇运动、截面力矩和船体振动激励。与CFD方法不同的是,本文采用了基于位势流的全非线性耐波性模拟,并进行了经验修正。这将计算工作量减少了几个数量级。与其他计算和模型实验的比较表明,该方法的精度不低于其他最佳计算和模型实验的精度。经过大约十年的发展,该方法已经成熟,可以用于常规应用。如果向无国界医生组织捐赠足够的礼物,该程序的源代码可以从作者处获得。

Nonlinear seakeeping and hydroelasticity of ships using potential flow simulations
ABSTRACT Accurate predictions of the behavior of ships in steep regular waves or in a natural seaway must take into account nonlinear wave responses, especially for roll motions, section moments, and hull vibration excitation. In contrast to CFD methods, here fully nonlinear seakeeping simulations are presented based on potential flow with empirical corrections. This reduces the computing effort by several orders of magnitude. Comparisons with other calculations and model experiments for benchmark cases show that the accuracy of the present method is not worse than that of the best other computations and model experiments. After about ten years of development, the method appears mature for routine applications. The source code of the program is available from the author if an adequate gift is donated to the Mèdecins Sans Frontières.
