摘　　要：针对于科考船多波束导流罩设计和船体线型设计缺少关联分析的主要问题,介绍了一种科考船导流罩线型与船体线型一体化CFD分析方法,综合考虑实船航行过程中船体型线和导流罩型线之间的相互影响。根据这种分析方法,分别对导流罩和船体组合线型的阻力性能和防气泡性能进行了CFD预报,并进行了船模试验。两者吻合良好,验证了此种CFD分析方法的工程实用性。The design process of the research vessel and the fairing of multi-beam echo sounder lacks correlation analysis. In order to solve the problem, a new CFD integrated analysis method is designed in this paper, considering the interaction between hull lines and profile of the fairing during the sailing. The method was used to predict resistance performance and anti-bubble performance of the combination of the hull and the fairing. The ship model test was also carried out. A comparison of numerical and experimental results shows a fair agreement, indicating the practicability of the analytical method.
