Design of the Matching Pipeline Intake of Water Ramjet with Supercavitating Vehicle
摘要
Abstract
The reasonable and efficient structure of water pipeline′s intake,especially the matching properties are the vital issues in the design process of water ramjet of supercavitating vehicle.On the basis of analyzing the properties of exterior flow field of supercavitating vehicle and the requirements of the water ramjet,this paper advances a scheme of matching the pipeline intake of water ramjet with the supercavitating vehicle.The numerical model of match scheme is built,and the relations between matching parameters and object parameters are achieved.The analysis results indicate that： with the increase of non-dimentional length of the pipeline intake that stands out to the cavitator,both recovery coefficient of pressure and flow rate are increased,and it reaches the maximum values when non-dimentional length of pipeline is 0.2,then they decline;with the increase of the intake area,both of them increase monotonously;the partial lose of pressure of pipeline intake become minimum when non-dimentional length of pipeline is 0.2,the non-dimentional length of pipeline intake that stands out to the cavitator and the intake area are is the main design variables.关键词
