在陡峭的冰道上航行时，船舶阻力会显著增加。本文应用数值方法对散货船在急冰航道中的实船阻力进行了预报。将粘性流动计算流体力学(CFD)求解器与离散单元法(DEM)相耦合，建立了突冰模型。采用欧拉多相流的流体体积(VOF)模型来模拟船体与水的相互作用。对船舶与急流冰相互作用进行了数值模拟。将基于数值方法和芬兰瑞典冰级规则(FSICR)的船舶总阻力预测结果与在汉堡船模水池(HSVA)上进行的试验结果进行了比较。数值计算结果与HSVA实验结果吻合较好，且比FSICR方法具有更好的性能。研究表明，该数值方法可以为工程应用提供合理、实用的抗冰力预报。
Ship resistance increases significantly when navigating a brash ice channel. In this study, the numerical method is applied to predict the full-scale ship resistance of bulk carriers in brash ice channels. The viscous flow computational fluid dynamics (CFD) solver was coupled with the discrete element method (DEM) to establish the brash ice model. The Euler multiphase flow’s volume of fluid (VOF) model was applied to simulate the interaction between the ship and water. The ship–brash ice interaction was simulated. Predictions of ships’ total resistance based on the numerical method and the Finnish Swedish ice class rules (FSICR) method were compared with the experimental results carried out in Hamburg Ship Model Basin (HSVA) ice tank. The numerical resistance shows a good agreement with the HSVA experiment reports and a better performance than the FSICR method. The present study shows that the numerical method could provide reasonable and practical ice resistance predictions for engineering applications.
