减摇鳍与舭龙骨不同组合方式对船舶快速性影响研究

摘要

通过计算流体力学数值仿真以及模型试验的方式对3种组合方式下(2对固定式减摇鳍+连续式舭龙骨、前面1对固定式减摇鳍+连续式舭龙骨、舯部1对固定式减摇鳍+间断式舭龙骨)的船舶快速性进行对比分析,并对后2种组合方式的减摇鳍做全收放式考虑,分析减摇鳍不工作对静水阻力及航速的影响,得到了减摇鳍与舭龙骨不同组合方式下对快速性的影响规律及相关的定性及定量结论,可用于指导附体设计和快速性优化.%Contraposing three combinations of fims and bilge keels (continuous bilge keels and two pairs of fixed fims、continuous bilge keels and a pair of fixed fims in front of them、discontinuous bilge keels and a pair of fixed fims in middle of them),the speeding of ship is compared by CFD method and model test.Moreover when the fims in after two combinations are extension ones and entireiy in ship in unworking condition,the resistance and speed in calm water are analysed.Therefore the influence on speeding in different combinations of fims and bilge keels is gained and the relevant conclusion can be used in ship design and speeding optimization.
