【摘要】 本文通过介绍引射器的基本工作原理及其特性 ,归纳了人们对于引射器建立模型的分析方法 ,指出虽然对引射流场已有较精细的分析 ,但由于流动的复杂 ,目前仍是以一元均匀流为主。本文从三个方面介绍了工程中人们感兴趣的几个重要理论研究、工程应用及现状。更多还原

【Abstract】 The basic principles and characters of ejection are presented in this paper. Analytical method for establishing physical-mathematical model has been deduced. Owing to the complexity of flow, computation of the flow parameters is mainly based on the theory of one-dimensional uniform flow, not withstanding the research results already got. New trends in theoretical investigation and advances of technical applications are quoted.更多还原
