摘    要:中高速船在航行状态下,其航态与低速航行相比有较大的不同,对船舶的阻力有明显的影响。因此,此类船舶的阻力预报必须考虑船舶航行姿态的影响。现有公开发表的关于滑行艇垂向+纵向运动理论预报研究的资料不多见。基于Flu-ent平台对三维船体航态对阻力的影响进行研究,采用动网格技术模拟船舶的航态;同时,为了保证计算的连续性与稳定性,利用FLUENT二次开发平台,编写UDF程序,在离散的时间域内根据船体的受力对船舶运动进行干涉。计算结果表明该方法对船舶的水动力预报问题具有可行性。

关 键 词:船舶阻力预报  航态  动网格  UDF

Abstract:High-speed boat's navigation State, compared with the low-speed boat is quite different. It has a significant impact on the ship's resistance. The resistance prediction of such vessels must need consideration of the impact of the ship's navigation state. Existing published information about the planning craft vertical and longitudinal movement theory prediction research is rare. The author mainly use the dynamic mesh to simulate ship navigation state. At the same time, in order to ensure the calculation continuity and stability, in discrete time domain, according to the force of the hull, UDF was used to control the ship motion. This paper is about basing on fluent to calculate the three-dimensional hull resistance, taking into account the navigation state. The calculation results show that the method of ship hydrodynamic prediction is feasible.
Keywords:Ship resistance prediction  Navigation State  Dynamic mesh  UDF
