50 m围网渔船波浪增阻数值模拟
|
摘要
以一艘50 m围网渔船船模为研究对象,采用STAR-CCM软件计算研究其约束运动模型在静水和迎浪情况下的阻力及相关性能。通过船模试验验证了STAR-CCM对渔船静水运动数值模拟的有效性。对渔船船模约束模型在不同波高、不同波长的波浪中的阻力进行计算和比较,研究了纵倾和升沉情况下渔船在波浪中的阻力计算结果的差异,结果表明渔船在波浪中的总阻力计算结果随波高和波长的变化存在一定差异,实际航行中波浪增阻会造成约0.5 kn的航速损失。
Using STAR-CCM software, a 50 m purse seine fishing boat model is used to calculate and study the resistance and relative performance of the constrained motion model under static water and wave. The effectiveness of STAR-CCM in numerical simulation of fishing vessel in hydrostatic motion is verified by model test. The model of ship model restraint is calculated and compared, and the results of the calculation of the wave resistance are studied when considering the vertical tilt and the rising of the ship. The results show that the total resistance calculation results of the fishing boat in the wave are different with the change of the wave height and wavelength. The wave added resistance in the actual navigation will cause about 0.5 kn of speed loss.
