| 摘 要： | 为了克服船舶现有堵漏手段固有的不足,提出涡旋流堵漏的新技术思想.设计制作了相应的试验装置,研究刚性桨叶工作位置对涡旋流堵漏效果的影响.结果表明:当刚性桨叶与破口处于同一高度且距离破口越近时,对降低破口进水量的效果越明显,可用于堵漏的时间延长到300%以上.研究结论可为船舶涡旋流堵漏方法的完善提供理论基础和试验依据.

| Abstract: | The leak stopping method based on vortical flows is a new technological idea to overcome shortcomings of traditional leak stopping method of warship.A set of experiment equipments were designed and manufactured,and the relationship between the leak stopping effect of vortical flows and working depth of rigid propeller was studied.The results show that,with the distance between propeller and leak being shorten,the decrease of water flow rate is significant when depth of the rigid propeller beneath water is s... |
