- As the jet angle decreases, the recirculation zone on the left side becomes smaller than that of the right side. 当射流倾角减小时，左侧回流区的范围变小，而右侧的回流区增大。
- 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；
- Based on the technique of the grading fire in recirculation zone,a slit bluffbody burner has been designed and applied to the power boiler in BaoSteel Power Plant for the combustion of poor blast furnace gas(BFG)instead of old type burners. 将回流区分级着火技术应用于低热值高炉煤气（BFG）燃烧，设计了高炉煤气开缝钝体燃烧器，用于宝钢自备电厂1160t/h锅炉，代替原日本设计的隔栅式直流燃烧器。
- By the comparison of simulation results and experiment data, the subgrid scale models can simulate the transient turbulent flow and recirculation zone behind the bluff body stabilizer. 通过计算结果及实验数据的比较可知，本文采用的亚网格尺度模型可以用来模拟模型燃烧室紊流流场及稳定器后面回流区的流动情况。
