bluff body

基本解釋

Research results of the cold aerodynamic flow characteristics of a bluff-body flame stabilizer mounted on the outlet of a tangential burner are reported.
本文主要介紹在直流式燃燒器出口加裝鈍體穩(wěn)燃器后的冷態(tài)空氣動力特性的研究成果。
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.
研究結(jié)果表明，對于鈍體穩(wěn)定火焰，SSG模型以及兩個(gè)修正后的LRR IP模型要優(yōu)于其他幾個(gè)二階矩封閉湍流模型。
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.
實(shí)驗(yàn)證明，根據(jù)這一原則設(shè)計(jì)的開縫純體燃燒器對低揮發(fā)分煤粉的著火與火焰穩(wěn)定具有較好的適應(yīng)性。

鈍體
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%.
從模擬結(jié)果得出,開縫V 形鈍體在縫寬率為36%時(shí),其火焰穩(wěn)定能力和阻力特性綜合性能達(dá)到最佳。
