| 摘 要： | 对三级轴向旋流器燃烧室进行了不同进口速度、进口温度、三级轴向旋流器旋向组合和空气流量分配下的贫油熄火性能试验.研究结果表明:随着进口速度、进口温度的增加,三级轴向旋流器燃烧室的贫油熄火油气比减小,进口温度的升高对贫油熄火性能的影响显著;相同进口速度下旋向组合为逆时针-逆时针-顺时针方案的贫油熄火油气比比旋向组合为顺时针-逆时针-顺时针方案的贫油熄火油气比约高50%;内旋流器空气流量的减小可使得贫油熄火油气比有所减小,但减小的幅度不大.

| Abstract: | Experiments were conducted to study the lean blowout (LBO) performance of triple axial swirler combustor at different inlet airflow velocities, inlet airflow temperatures, triple axial swirler rotational direction combinations and airflow mass flow rate distributions. The results show that: the lean blowout fuel-air ratio (LBO FAR) of triple axial swirler combustor decreases with increasing inlet airflow velocity and inlet airflow temperature, and inlet airflow temperature has great effect on LBO performance; the LBO performance of scheme with rotational direction combination of counterclockwise-counterclockwise-clockwise is improved by about 50% compared with that of clockwise-counterclockwise-clockwise at the same inlet airflow velocity; the LBO FAR decreases to a little extent when the inner swirler airflow mass flow rate decreases. |
