| 摘 要： | 设计了一套可溶气体析出气泡雾化系统,将二氧化碳在高压下溶入水中达到饱和状态,经节流孔降压后,二氧化碳在喷嘴的混合室内析出和水形成气液两相流,最后由喷嘴喷出.通过对两种类型的气泡雾化喷嘴进行喷雾实验,并利用三维激光颗粒动态分析仪(Dual PDA)进行数据采集和处理,对喷嘴出口下游平均速度分布和喷雾D10、D32:Dv0.9三种平均直径进行了理论分析,结果表明该方法完全可行,雾化质量很好,同文献中提到的其它气泡雾化喷雾平均直径相比平均直径更小.两种喷嘴中,加旋流的A型喷嘴雾化效果更好.

| Abstract: | A new effervescent atomization system was designed in this paper.In this system,carbon dioxide was dissolved into water under certain pressure until the saturated condition.When the saturated liquid passed the throttle orifice,its pressure declined.Then the water and carbon dioxide formed two-phase bubble flow in the mixing chamber of nozzle and sprayed from the exit orifice of nozzle.In order to examine the feasibility of this system,data were collected,processed and analyzed with Dual PDA for two kinds of... |
