bluff body

基本解释

Research results of the cold aerodynamic flow characteristics of a bluff-body flame stabilizer mounted on the outlet of a tangential burner are reported.
本文主要介绍在直流式燃烧器出口加装钝体稳燃器后的冷态空气动力特性的研究成果。
It can be concluded that the modified LRR-IP models as well as SSG model are superior to other SMTC models in the turbulent nonpremixed bluff-body stabilized flame.
研究结果表明，对于钝体稳定火焰，SSG模型以及两个修正后的LRR IP模型要优于其他几个二阶矩封闭湍流模型。
Experiments show that a new-type pulverized coal burner with a slit bluff-body designed on the said principle is suitable for the ignition and flame stability of low volatile pulverized coal.
实验证明，根据这一原则设计的开缝纯体燃烧器对低挥发分煤粉的着火与火焰稳定具有较好的适应性。

钝体
The evidence shows that the V shape slitted bluff body has the best flameholding ability and the lowest drag at a gap ratio of 36%.
从模拟结果得出,开缝V 形钝体在缝宽率为36%时,其火焰稳定能力和阻力特性综合性能达到最佳。
