摘要
为研究某海洋工程船舶减摇水舱液体晃荡的固有周期及其阻尼特性,设计有机玻璃模型,开展模型试验。利用开源软件OpenFOAM开发基于两相流求解器InterFOAM的计算程序包,对该减摇水舱模型液体晃荡的固有周期和阻尼进行数值预报,并讨论模型网格尺寸、水舱阻尼板、水舱液面高度等因素对固有特性的影响,预报结果与模型试验结果吻合较好。研究成果可为减摇水舱的设计提供技术指导。
In order to investigate the Eigen characters of the anti-rolling tank of an ocean engineering vessel,a model is designed and made using polymethyl methacrylate plates.The model tests are carried out.A program based on the two-phase flow solver InterFOAM is developed using the code OpenFOAM.The parameters of the natural period and damping are predicted.The effects of the model mesh size,damping plates,tank water height on Eigen characters are discussed.The numerical and experimental results show fairy well agreements.The results can be applied to design the anti-rolling tanks.
