气液同轴旋流式喷嘴喷雾特性实验研究
Experimental Study on Spray Characteristics of Gas-liquid Coaxial Swirl Injector
以软化水为工质，对一种气液同轴旋流式喷嘴开展了实验研究，首先分析宏观雾化特性，探讨喷雾流量和雾化锥角随供水压力和供气压气的变化规律；然后分析二次雾化粒子特性，探讨粒径分布和液滴速度的分布规律。结果表明，喷嘴流量随水压上升而上升，而气路的压力变化不会明显影响喷嘴的流量；随供气压力的上升，雾化锥角开始收缩，气体压力不变时，随着供水压力的上升，雾化液锥向外扩张，当供水压力达到一定值后，随着供水压力的上升，雾化锥角增长缓慢。距离喷嘴出口一定距离后，喷雾破…查看全部>>
An experimental study was carried out on a gas-liquid coaxial swirl nozzle with softened water as the working fluid. Firstly, the macroscopic atomization characteristics were analyzed, and the variation of spray flow rate and atomization cone angle with water supply pressure and air supply pressure was discussed. Then, the characteristics of secondary atomization particles are analyzed, and the distribution of particle size distribution and droplet velocity …查看全部>>
