| 摘 要： | 应用面元法对淹没水射流锥形喷嘴流动特性进行了简要的计算，并结合试验结果作了分析与比较，指出分析不同结构喷嘴内部及射流区域内的压力系数分布，可以得出喷嘴的收缩角α及圆柱段Ｌ与喷嘴冲蚀性能之间的关系，为对喷嘴的进一步研究提供了理论指导。

| Abstract: | By using the panel method,the fluid field of submerged water jet noaales is calculated and the numerical results are compared with the experimental.Through analyzing the distribution of pressure coefficients,it is shown the erosion performance is related to both the conical contraction angle and the cylindrical section of nozzles.It provides the theoretical foundation for further studying of conical nozzles. |
