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,而对液相流量的影响规律却不同
In this paper, the flow characteristics of two different types of gas-liquid coaxial nozzles were studied experimentally. The effects of the gas-liquid interaction and the back pressure on the flow characteristics of the nozzles were mainly studied. The results show that the coaxial The gas-liquid interaction in the centrifugal nozzle is stronger than the gas-liquid interaction in the coaxial direct-flow nozzle. For these two nozzles, the influence of the change of backpressure on the gas flow is the same, but the influence on the liquid flow is different
