摘　　要：为消除浮标作业船在海上航行过程中因海浪破碎而产生的气泡对船侧及船底多波束装置的影响,提升其测量精度,对该装置加装多波束导流罩,根据船舶总体布置方案设计2种多波束导流罩安装位置。通过CFD(Computational Fluid Dynamics)数值模拟技术分别在4级海况和静水情况下对该浮标作业船加装多波束导流罩之后的航行情况进行数值评估,并对其防气泡性能和阻力性能进行CFD预报和分析。结果表明:在4级海况下,2种安装位置的防气泡性能并无明显差异;在静水条件下,2种安装位置各有特点,且导流罩攻角对船体周围流场的影响巨大。该研究可为浮标作业船加装多波束导流罩提供参考。For installation of fairing of multi-beam device on existing buoy tender,eliminating the influence of air bubbles,two different installation positions are proposed by the overall layout plan.By CFD(Computational Fluid Dynamics)numerical simulation,the ship performance assessments for the buoy tender to be equipped with the fairing are carried out both in moderate sea and calm water sea conditions.The anti-bubble property and resistance are predicted and analyzed.The results show that,for the two different installation positions,there is no significant difference in anti-bubble in moderate sea,while in calm water,different installation positions lead to different performances and the deflector angle of attack has a huge impact on the flow field around the hull.
