Abstract

In this study, the added resistance and seakeeping performance of the KVLCC2 ship is investigated by using the spectral wave explicit Navier-Stokes equations (SWENSE) method. The SWENSE method is based on the decomposition of the total field into an incident part explicitly obtained by the wave potential flow theory and a complementary part solved with a modified Reynolds-averaged Navier-Stokes solver. Therefore, the computational efficiency can be achieved by using a relatively coarse mesh in the far field, retaining the accuracy of the incident waves. A parametric study is performed under regular wave conditions with 3Degree of Freedom (DOF) motions of the hull. The results are compared with the large literature available. An additional case is simulated to demonstrate the capability of the present method in simulating seakeeping problems in irregular sea states. Good agreement between the computed results with the reference data can be observed for the hull model, which indicates that the added resistance and seakeeping performances can be well predicted by the present method.

SWENSE法对KVLCC2附加阻力和适航性能的数值研究

本研究采用谱波显式Navier-Stokes方程（SWENSE）方法研究了KVLCC2船舶的附加阻力和耐波性。SWENSE方法基于将总场分解为通过波势流理论明确获得的入射部分和通过改进的雷诺平均Navier-Stokes解算器求解的互补部分。因此，可以通过在远场中使用相对粗糙的网格来实现计算效率，同时保持入射波的精度。在规则波浪条件下，对船体的3自由度（DOF）运动进行了参数研究。将结果与现有的大量文献进行了比较。另外还对一个实例进行了模拟，以证明本方法在模拟不规则海况下的耐波性问题方面的能力。船体模型的计算结果与参考数据吻合良好，表明该方法可以很好地预测附加阻力和耐波性能。

期刊介绍： Original and Timely technical papers addressing problems of shipyard techniques and production of merchant and naval ships appear in this quarterly publication. Since its inception, the Journal of Ship Production and Design (formerly the Journal of Ship Production) has been a forum for peer-reviewed, professionally edited papers from academic and industry sources. As such, it has influenced the worldwide development of ship production engineering as a fully qualified professional discipline. The expanded scope seeks papers in additional areas, specifically ship design, including design for production, plus other marine technology topics, such as ship operations, shipping economic, and safety. Each issue contains a well-rounded selection of technical papers relevant to marine professionals.
