基于CFD的滑行艇全航速段操纵性能研究
|
摘要
在全航速段航行的滑行艇其航态随航速变化剧烈,导致其操纵水动力性能非常复杂.目前滑行艇在全航速段操纵性能方面的研究并不多见,需要深入研究.文中针对某喷水推进滑行艇在不同航速段下的操纵水动力及其操纵航行性能问题开展研究,采用CFD(computational fluid dynamics)方法模拟计算在不同航速下的操纵水动力,并仿真其自航操纵试验,最后对影响滑行艇操纵运动的因进行分析.计算和仿真的结果表明,文中采用的方法能够较好地模拟、分析滑行艇的操纵航行性能,并得到了一些有用的结论.
The navigation state of a planing boat sailing at full speed varies greatly with the speed,resulting in very complicated hydrodynamic performance.In this paper,the control hydrodynamic force and the control navigation performance of a water jet propulsion planing boat at different speeds were studied.CFD(Computational Fluid Dynamics)method was used to simulate the control hydrodynamic force at different speeds,and its self-navigation control test was also simulated.Finally,the factors affecting the maneuvering of the planing ship were analyzed.The results of calculation and simulation show that the method adopted in this paper can better simulate and analyze the maneuvering navigation performance of the planing ship and get some useful conclusions.
