本文针对可调加热器用燃烧室的需要，设计了两种新型旋流多级气动雾化喷嘴，并对雾化性能进行了实验研究，探讨了影响喷雾特性的主要因素，评价了喷雾场．研究了最佳喷嘴结构形式，在模拟工况下雾化性能良好，适合小流量燃烧室工作需要，ＳＭＤ接近 ２５ μｍ．
In this paper, two new types of swirling multi-stage aerodynamic atomizing nozzles are designed to meet the needs of the combustor for adjustable heater. The atomization performance is studied experimentally. The main factors influencing the spray characteristics are discussed and the spray field is evaluated. The optimum nozzle structure was studied. The atomization performance was good under simulated conditions, which was suitable for the work of small flow chamber. The SMD was close to 25 μm.
