摘　　要：以自主研发的弱尾迹浸没式喷水推进系统为研究对象,应用CFD方法,将自适应网格(AMR)技术与流体体积模型耦合,开展数值模拟,探索该技术应用于喷水推进船舶自航的可行性。将仿真结果与模型试验数据进行比较,表明基于AMR技术的喷水推进船舶自航模拟方法可获得较高的精度,能大范围捕获流场信息,且选取的浸没式喷水推进器在中低航速时能有效抑制尾迹。In this paper,the weak wake submerged water jet propulsion system developed independently is taken as the research object,and the CFD method is used to couple the adaptive mesh refinement(AMR)technology with the Volume of Fluid model.Experiments show that the self-model simulation method based on AMR can obtain high accuracy and capture the flow field information in a large range.
