摘要
随着舰船大型化和快速化的发展,舰船易发生横倾和纵倾等浮态变化。如何准确地预报舰船的阻力状况是设计船体时的重要步骤。针对此问题,本文主要采用计算流体动力学的方法估计舰船阻力。本文在介绍CFD技术原理的基础上,研究了CFD主要技术思路和详细计算流程。对船体在航行过程中所受阻力进行归纳分类,推导流体动力学控制方程式,研究应用广泛的湍流模型。最后,进行船模试验,验证CFD模拟计算结果。试验结果表明,CFD计算结果较为精确,具有实际应用价值。
With the large-scale and rapid development of ships, the ship tends to change in the state of the dip and trim.How to predict the ship's resistance accurately is an important step in designing a ship hull. To solve this problem, this paper mainly uses computational fluid dynamics to estimate ship resistance. On the basis of introducing the principle of CFD technology, the main technical ideas and detailed calculation flow of CFD are studied. The resistance of the ship during the voyage is classified and the hydrodynamic control equations are derived, and the turbulence model is studied. Finally, ship model test is carried out to verify the results of CFD simulation. The experimental results show that the CFD calculation results are more accurate and practical.
