| 摘 要： | 利用PIV测量技术,通过试验研究了两种双流体雾化喷嘴（气泡雾化喷嘴和Y型喷嘴）的雾化特性,分析了气液比、液体流量、喷嘴结构等对雾化性能的影响,研究结果表明：气泡雾化喷嘴的雾炬比双流体喷嘴更饱满,雾化质量更好;雾化颗粒平均粒径随着气液比增加呈现下降趋势,当ALR〉0.04,雾化颗粒平均粒径减小的趋势趋缓;随着被雾化液体流量的增加,雾化颗粒平均减小;在相同混合室面积条件下,增大雾化气注入孔截面积有利于雾化质量的提高.

| Abstract: | Atomizing characteristics of two kinds of twin-fluid nozzles(effervescent nozzle and Y-type nozzle) are experimentally studied by using PIV technology;the influences of nozzle type,air to liquid ratio(ALR),liquid flowrate,nozzle internal geometry,etc on atomizing properties are analyzed.The atomizing experimental results show that atomization quality of effervescent nozzle is better than that of Y-type nozzle under the same condition;Sauter mean diameter(SMD,D32) of atomized particles decreases with increas... |
