【摘要】 拖网渔船在海洋渔船中占有很大份额,具有多工况、船型复杂的特点,是渔船节能专向研究的重点对象。文中将CFD技术应用于该船型的阻力计算,考虑自由水面效应,计算出相应航速下的阻力值,与模型试验结果吻合度较高,可以在进一步深入研究其影响因素的前提下部分取代模型试验的效果。更多还原

【Abstract】 As the majority of ocean fishing ships,featured with multi-operating modes and complex forms,trawlers become an important point in the energy-saving research field.In this paper,viscous computational fluid dynamics(CFD) technology is applied to resistance computation of a trawler.Taking the free surface ef-fect into consideration,the total resistance of model at several corresponding speeds is obtained.Numerical re-sults coincide well with model test data,showing that CFD technology can partly displaced model tests as an effective method in the research of fluid dynamic performance of a fishing vessel.更多还原
