摘　　要：　介绍了一种气气喷射流快速混合技术,利用射流的碰撞及卷吸所产生的流动特性促进2股气体的快速混合。对影响混合质量的各种参数:动量比MS/Mb、开孔直径d、开孔面积S及混合长径比L/D等分别进-0.44ds0.73d20.30+0.015,对-0.53d2ssb行了探讨,在此基础上建立了一个经验模型S=0.23ρsu2DsSsSbρbu2b气体喷射流快速混合器的设计和工程放大有参考价值。A new technique of gasgas ejecting rapid mixing was proposed, in which the flow characteristics caused by impingement and swirling between two streams promote gasgas rapid mixing. The parameters that affect the mixing quality have been studied, such as momentum ratio, pore diameter, area and the ratio of length to diameter. A experiential model has been set up, which could be in use of the design and amplification of the gas ejecting mixer.
