摘　　要：本文旨在设计并实现一种新型泡沫喷射装置,通过调整其收敛角的角度及进气口与进液口的长度差,泡沫有效喷射距离显著提高至46.7 m。此外,还构建了模拟模型,分析该装置在泡沫两相流中的流动特性,并研究了几何特征、出口气体体积分数(反映发泡效果)与其喷射射程之间的关系。试验结果显示,该装置的性能验证准确率为93.27%。研究成果对于提高泡沫灭火剂的发泡性能和效率,以及研发高性能的泡沫枪与灭火系统具有重要意义。The study focuses on developing a novel foam jetting device through adjustments to its convergence angle and inlet/inlet length disparity.This enhancement resulted in an increased effective shooting distance of foam at 46.7 m.Furthermore,the paper presents a simulation model that examines the flow dynamics within the two-phase foam stream and investigates the relationship between geometric features,gas volume fraction at the outlet(indicative of foam generation efficacy),and the range of jetting.The experimental results confirm an accuracy rate of 93.27%in device performance verification,contributing to advancements in foam extinguishing agent foaming efficiency and the development of high-performance foam guns and fire suppression systems.
