处于由离心力和科里奥利力构成的大加速度场中的燃烧过程,其熄火极限会发生较大的变化.作者通过对液化石油气和空气的预混火焰和扩散火焰在不同的空燃比(AFR)下,在气流喷射方向与燃烧器旋转切线方向垂直、相同或相反三种情形时分别作了试验,得出了离心力和科里奥利力对预混和扩散火焰的熄火的影响规律.“,”When combustion happens in a large acceleration field that made from of centrifugalforce and Coriolis force, the extinction limits of combustion would largely change, and theflame fronts would change with the strength of the acceleration field. The experiments arecarried out to premixed flames and diffusion flames in different AFR (flux of air-fuel ratio)and in three cases, in which the gas flow jet direction is vertical to, same as or adverse tothe rotating tangent direction. The experimental results reveal the law of the influences oflarge acceleration field on eXtinction of premixed flames and diffusioll flames.
