滑行艇阻力计算方法对比研究

Comparative study on simulation of resistance for planing craft

摘要

摘要:
目的小型快艇具有机动灵活、隐蔽等特点，滑行艇作为小型快艇的重要种类，被广泛应用于民用和军事用途，因而准确计算滑行艇阻力对滑行艇性能的改进就显得尤为重要。
方法首先，基于根据美国62系列滑行艇船型资料设计得到的一型滑行艇，分别运用半理论半经验方法和CFD方法对该型艇模型阻力性能进行计算，然后，通过船模试验予以验证并对采用各种方法所得计算结果进行分析。
结果研究表明，半理论半经验方法可以较好地模拟该型滑行艇阻力变化趋势，CFD方法在高速滑行状态下可以达到较高的计算精度，最小误差仅为0.38%。
结论所得结果表明STAR CCM+软件能够有效模拟该型滑行艇的阻力性能，而在具体计算中采用何种方法则可根据所需精度和条件进行相应的取舍和选择。

Abstract:
Objectives The small high-speed crafts have many advantages such as good mobility and concealment.As an important part of the small high-speed crafts, the planing crafts are widely used in civil and military applications.So the accurate simulation of the resistance of the planing craft is particularly important for improving the performance of the planing craft.
Methods We herein calculate the resistance of a planing craft based on American planing craft series 62 using the analytical-experimental method and CFD method respectively.Then we make a verification through the ship model test and analyze the results of each method.
Results It shows that the results of the analytical-experimental method are in well agreement with the trend of the planing craft resistance, while the CFD method can achieve high accuracy with a minimum error of 0.38% under high speed planing condition.
Conclusions STAR-CCM + software can effectively simulate the resistance of this planing craft, and either of the methods can be used depending on the required precision and conditions.
