基于CFD技术的2800 TEU船线型优化

The Hull Form Optimization of 2 800 TEU Ship Based on CFD Technology

基于CFD技术对线型优化是目前业界比较流行的做法。文章依托实船2800 TEU船项目,探索基于NAPA和CFD软件的一体化优化(传统经验模式)和基于CAESES和CFD软件的一体化优化(先进数值评估模式)的有机结合,以船模阻力系数为目标函数,对线型优化。结果显示,航速达到优化目标要求。

It is a more popular practice in industry at presents that hull form optimization based on CFD technology.Relying on the 2800 TEU ship project,the organic combination is explored of integrated optimization based on Napa and CFD software(traditional empirical mode)and integrated optimization based on caeses and CFD software(advanced numerical evaluation mode),and the resistance coefficient of ship model is taken as the objective function to optimize the line shape.
