| 摘 要： | 为准确预报喷水推进器设计工况与非设计工况的水动力性能,采用CFD方法对喷水推进器性能预报所需流场控制体进行了研究.在验证计算方法和数值模型可信的基础上,通过对比不同流场控制体的计算结果,分析了流场控制体对喷水推进器性能预报的影响.首先,确定了设计工况下流场控制体的大小;然后,对非设计工况下流场控制体的选取进行了分析讨论.结果表明,非设计工况下流场控制体的大小对喷水推进器性能预报的影响比设计工况大,而且非设计工况下所需流场控制体要大于设计工况时的情况.

| Abstract: | In order to predict the performance of waterjet exactly at design and off-design work conditions,the research on the effect of flow control volume was conducted by the CFD method.Based on the cred-itable method and numerical model,the effect of flow control volume on waterjet performance was analyzed by comparing simulation results of different flow control volumes.Firstly,the flow control volume for design work condition was confirmed,and then the analysis and discussion of flow control volume for off-desi... |
