摘 要:为探索研究高速深V型船新型减阻技术,针对高速深V船型艏部兴波的产生原因及兴波阻力的产生机理,提出了一种压抑船艏兴波以减小兴波阻力的减阻思路,获得了一种新型的船艏抑波减阻附体方法。以某具体的高速深V型船为对象,通过CFD数值模拟进行了目标航速下的抑波减阻附体的设计,在此基础上,利用高速船模拖曳水池进一步开展了深V型船艏部减阻附体方案效果的验证试验。结果表明,所设计的抑波减阻附体在水线长4.24m的船模上实现了目标航速(弗劳德数0.447)下总阻力减小6.67%、剩余阻力减小15.7%的效果,在实船尺度下该抑波减阻技术的减阻效果进一步增大。Study of drag reduction for a high-speed ship with a deep V formation was carried out. A method of suppressing the fore wave was presented and a new kind of fore appendage is designed to reduce wave making resistance. Taking a ship with a deep V formation as an example, this kind of appendage was designed with numerical simulation of CFD, and model ship towing test was carried out. It was shown that at the objective speed (Fr = 0.448),with the wave suppression and drag reduction appendage, the total resistance of the model ship could be reduced by 6.67% and the residual resistance could be reduced by 15.7%. The drag reduction effect could be enhanced for the full scale ship.
