摘要
本文通过实验方法对两种不同结构形式的气液同轴式喷嘴流量特性进行了研究,重点考察了喷嘴内气液相互作用和环境反压的变化对喷嘴流量特性的影响,研究结果表明同轴离心式喷嘴内气液相互作用比同轴直流式喷嘴内气液相互作用要强。对于这两种喷嘴,反压的变化对气相流量的影响规律相同。
This paper presents the result of an experimental study on the flowrate characteristics of coaxial swirling injector and coaxial unswirling injector. Effects of the interaction between gas and liquid flows in injector and the change of environmental pressure on the flowrate characteristics of injectors are investigated. The results show that the effect of the interaction between gas and liquid flows is much more significant for coaxial swirling injector than that for coaxial unswirling injector, and that increasing environmental pressure results in the same effects on the gas flowrate characteristics, but effects on the liquid flowrate characteristics for these two type injectors are different.
