| 摘 要： | 喷嘴是能量转换部件,其效率直接影响航行器的总体性能,如续航能力、航速等.根据喷嘴内部等压面的特征,运用量守恒定理,建立喷嘴内壁面压力分布模型.对两种喷嘴(圆柱、圆锥)内壁面压力分布进行仿真与试验研究.比较分析模型、仿真和试验的结果.因结果可知:①内壁面压力分布在接近喷嘴时急剧下降,且随孔径的增加,壁面压力变化率减小；②... |

| Abstract: | The nozzle,of which the efficiency has direct effects on the performance(such as endurance and speed) of watercraft,is an energy conversion component.Based on the features of isobaric surfaces,a pressure distribution model of the nozzle inner wall is built by utilizing the principle of conservation of energy.Simulation and experimental studies are carried out to investigate the inner wall pressure distributions of two kinds of nozzles(cylindrical nozzle,conical nozzle).Comparison analyses are performed amon... |
