用热线风速仪测量了ＷＲ型（宽调节比）燃烧器一次风射流的速度分布，Ｖ形稳燃体尾迹回流区的大小，以及边风与一次风组合射流的速度分布。用Ｋ－ε方法进行了数值计算，并将计算结果与实验结果进行了比较，试验和计算结果都表明，Ｉ边／Ｉ１，对射流半速度宽度和射流中心回流区有显著的影响；一次风口中的Ｖ形稳燃体和扩口角对稳定着火和适时补氧有明显的作用。
The velocity distribution of the primary air jet of WR type (wide air ratio) combustor, the size of the wake region of the V-shaped steady combustion wake and the velocity distribution of the combined jet of the edge wind and the primary air were measured with a hot wire anemometer. The K-ε method was used to calculate the numerical results and the results were compared with the experimental results. The experimental results show that I / I1 has a significant influence on the half-width of the jet and the jet center reflow zone. The V-shaped stable body and flare angle on the stable fire and timely oxygen has a significant role.
