摘要: 为了预估渔船实船阻力,以一艘11.75 m渔船为研究对象,基于CFD方法给出了一套完整的由船模阻力数值仿真到实船阻力换算的方法。结果表明:该方法可以有效地预估渔船船体阻力,减少设计成本;结合船舶在水中的垂向水动力,对阻力曲线中的峰值点和谷值点成因进行了分析,阐释了船舶阻力随航速的增加先增大后减小的原因。

关键词: CFD, STAR-CCM+, 阻力, 垂向水动力, 峰值点, 谷值点

Abstract: To pre-estimate the full-scale fishing ship resistance, this paper takes a 11.75 m fishing ship as the research object,and a complete set of methods is developed to convert the numerical simulation result of the ship model to a full-scale ship based on the CFD method. The results denote that this method can effectively estimate the hull resistance of the fishing ships and reduce the design cost. Based on the vertical hydrodynamic of the ship, the reasons for the peak point and valley point on the curve of the resistance are analyzed explaining the manner in which the resistance increases initially and subsequently decreases with increasing speed of the ship.

Key words: CFD, STAR-CCM+, resistance, vertical hydrodynamic, peak point, valley point
