灵便型散货船线型方案优化研究

摘要

Lines optimization research of a handy-size bulk carrier is done with software FRIENDSHIP and SHIPFFLOW. Model test is carried out to verify the optimization. CFD calculation results indicate that application of barge type to the after body can get benefit for resistance reduction, which is proved by model test. Then, lines optimization of the fore body is done with CFD software. Wave resistance is reduced a lot after the optimization, by which a better plan of lines is gained.%使用软件FRIENDSHIP 和SHIPFLOW对现有的灵便型散货船做线型优化研究，并通过船模试验进行验证。CFD计算结果表明，采用平驳型（barge type）后体有一定的减阻效果，此推断与船模试验结果相吻合，验证了软件计算的可信性。然后使用CFD软件对船舶前体线型作进一步的优化设计，大幅降低了兴波阻力，取得了较好的线型优化效果。
