摘要:对快速性技术指标较好的某化学品船进行线型优化研究。利用GMS前处理软件对船体线型进行若干变化,利用势流兴波软件RAPID进行快速计算,得到船体周围兴波及船体表面压力分布情况,从面选择较优方案。利用商业软件STAR-CCM对原型和改型的阻力性能进行黏性流体数值计算,定量分析改型后船舶力的减小量,为模型试验提供参考依据。模型试验结果表明,改型船的阻力较原型进一步降低,与计算流体动力学(Computa-

Abstract: The hull form optimization of a chemical tanker in terms of good speed and resistance performance is presented. The optimal scheme is decided according to the surface pressure distribution around the hull obtained from the calculation with the potential flow wave making software RAPID. Numerical caleulations of the viscous fluid resistance performance of the original and the optimized are performed by means of the commercial software STAR-CCM, The calculated resistance reduction is used as the reference basis of model tests, The model test data proved the success of the optimization and the reliability of CFD(Computational Fluid Dynamics) calculastion, The propulsion performance of the new matching propeller is significantly im-proved.
Key words: hull form optimization; CFD; model test
