- Therefore by regulating swirl number of combustor NO emission caw be reduced. 因此;适当调整燃烧室的旋流数可以降低NO排放.
- Swirl number should neither be too big, nor be too small.A big swirl number will widen the recirculation zone and cause drag increment. 旋流器的旋流数 对喷雾分布的影响比较复杂，旋流数增大，回流区随之变宽，但流动 阻塞比增加，降低流速；
- The effects of swirl number of primary swirler and radial swirler,area ratio and sleeve divergence angle on the cold flow field of double swirl air intake were investigated. 试验研究了主、径向涡流器旋流数、面积比、套筒扩张角等参数对双旋流进气装置冷态流场的影响。
- The distributions of gas temperature, O2, CO2, CO, and NO concentrations were measured under different swirl numbers for the primary air. 测量了在不同的一次风旋流数下,气体的时均温度、O2、CO2、CO和NO浓度的分布。
- The effect of swirl number on thermal No formation in swirling diffusion combustion is studied by numerical simulation, using the Reynolds stress equation turbulence model, EBU-Arrhenius combustion model and presumed-PDF NO formation model. 本文对旋流扩散燃烧进行了数值模拟，研究旋流数对热NO生成的影响，其中对湍流采用Reynolds应力方程模型，对燃烧采用EBU－Arrhenius模型，对热NO生成采用设定PDF的模型。
