【摘要】：針對(duì)先進(jìn)加力燃燒室火焰穩(wěn)定器采用的緊湊噴射模式,以包含一個(gè)鈍體穩(wěn)定器的矩形模型件為研究對(duì)象,數(shù)值研究了加力條件下來流溫度和速度以及噴口直徑、噴射距離、鈍體寬度對(duì)鈍體穩(wěn)定器后回流區(qū)局部當(dāng)量比的影響。結(jié)果表明:提高來流溫度、速度,擴(kuò)大噴口直徑,增加噴射距離或槽寬,都會(huì)增大鈍體回流區(qū)內(nèi)的當(dāng)量比。最后,利用獲得的數(shù)據(jù)建立了簡(jiǎn)單擬合函數(shù),以預(yù)估緊湊噴射模式下回流區(qū)內(nèi)的局部當(dāng)量比。
[Abstract]:In view of the compact injection mode used in the flame stabilizer of the advanced afterburner, a rectangular model with a blunt body stabilizer is studied. The temperature and velocity of the inlet flow, the diameter of the nozzle and the injection distance are numerically studied. The influence of the blunt body width on the local equivalent ratio of the backflow region of the bluff body stabilizer. The results show that the equivalent ratio of the bluff body in the backflow region can be increased by increasing the temperature and velocity of the inlet flow expanding the nozzle diameter and increasing the injection distance or slot width. Finally, a simple fitting function is established based on the obtained data to predict the local equivalent ratio in the reflux region under the compact injection mode.
