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.

A tom izing character istics of two k inds o f tw in-flu id nozzles ( e ffervescent nozzle and Y - type nozzle) are ex perim enta lly studied by using PIV techno logy; the influences o f nozzle type, a ir to liqu id ratio ( ALR), liquid flow ra te, nozzle inte rnal geom etry, e tc on atom izing prope rties are analyzed. The a tom izing exper im ental resu lts show that atom iza tion qua lity o f e ffervescent nozzle is better than tha t of Y- type no zzle under the sam e cond ition; Sauter mean diam eter ( SMD, D 32 ) of atom ized partic les decreasesw ith increas ing o f a ir to liqu id ratio, the decreasing degree reaches stability a t ALR> 0. 04; SMD of a tom ized partic les decreases w ith increasing of liqu id flow rate at the sam e a ir to liqu id ratio; it w ill be he lpful fo r atom ization qua lity fo r effervescent nozzle to increase the injection area o f atom iza tion air in the sam e a ir infection area of internal m ixture cham ber
