| 摘 要： | 对在燃烧室进口高速气流条件下工作的贫油双涡结构驻涡燃烧室,通过改变主流马赫数与温度和改变其凹腔几何尺寸进行贫油熄火性能试验.试验结果表明:①随着主流马赫数的增加,贫油熄火余气系数减小,主流速度是影响贫油熄火性能的最主要因素.②主流温度的升高对拓宽燃烧边界有利,但是在达到600K后,对贫油熄火余气系数的影响逐渐减弱.③双涡试验件后体进气量的增加可以使贫油熄火性能变差.④不同凹腔宽深比对贫油熄火余气系数的影响很大,综合各个试验件结果,深宽比为0.88的双涡试验件的贫油熄火性能最好.

| Abstract: | To investigate lean-blow-out(LBO) performance of trapped vortex combustor(TVC) in high inlet flow,experiments were employed by changing Ma and temperature of main air and height to length(H/L) of the cavity.The results of experiments show that:(1) Mach number of main air has great effect on LBO.When Mach number of inlet main air becomes bigger,LBO decreases.As Mach number of inlet conditions varies,the change of LBO is great.(2) Temperature rise of main air is conducive to LBO,but after 600 K,the effect is ... |
