主　　题：火焰 多环反向喷射 流场分析 

摘      要：The technique of the use of multi-annular opposed jets as different from using swirl and bluff body creates an excellent recirculation zone with desired size in a large *** size of ecirculation,the magnitude of reverse velocity and turbulence intensity are much greater than those formed by bluff *** affecting the flowfield include the velocity ration of the opposed jets to the primary air *** diameter and construction of the opposed jet ring,secondary air velocity and configuration,and confined or unconfined flow condition and so *** method is a promising way for flame stabilization in combustion technology.
