| 摘 要： | 针对已建成科考船加装中水多波束的实际技术需求,结合中水多波束加装科考船的船舶线型及其系统安装要求,通过设计两种不同类型的导流罩线型,并与船体线型一体化进行计算流体动力学(Computational Fluid Dynamics,以下简称CFD)仿真分析,了解实船舶航行过程中船体型线和导流罩型线之间的相互影响,分别对圆弧型导流罩和折角型导流罩的防气泡性能和阻力性能进行了CFD预报和分析。最后经海试验证折角型导流罩能够完全满足中水多波束的安装线型流线及湍流动能的性能指标,为科考船多波束导流罩的设计安装或加装提供一定的借鉴和参考作用。

| Abstract: | This paper is written to meet the need of actual technical requirements of installation recycled water multi-beam in the science researching ship which has been put in to use. Combined with the linear and system installation requirements of the ship, through the design of two different types of fairing lines, we analyzed linear unity by using Computational Fluid Dynamics(CDF) simulation analysis method in order to know the interaction influence between ship molded line and fairing molded line in sailing process. In addition, we have also used this tool to forecast and analyze bubble prevention performance and resistance performance between arc-shaped fairing and angle-shaped fairing. Finally, it is proved in sea testing that angle-shaped fairing can perfectly meet the linear of installing recycled water multi-beam and performance index of turbulence kinetic energy, which can provide some reference for design and installation of the multi-beam fairing for scientific research ships. |
