摘　　要：为克服现有堵漏手段的不足,提出一种新技术方法——船舶涡旋流堵漏方法。根据物理试验的具体情况,在利用Gambit软件完成桨叶实体和计算域模型建模的基础上,通过Fluent软件完成刚性桨叶生成涡旋流的数值仿真,根据仿真得到的涡旋流场速度矢量和压强分布,对试验得出的桨叶工作位置对破口进水量的影响规律进行理论剖析,进而从运行机理上揭示桨叶位置与涡旋流形成效果的关系。The leak stoppage method with special vortical flows is a new technological idea to fill the gaps of traditional leak stoppage methods for warships.The model of the rigid blade and the calculation domain based on physical tests with Gambit are constructed and the numerical simulation of the rigid blade produced vortex flow is conducted by Fluent.Based on the calculated vortex flow velocity vector and the pressure distribution,the relationship between the inflow at the break and the blade position are theoretically studied.
