摘要
基于计算流体动力学(CFD)技术,采用涡耗散燃烧模型对环形混合器和锯齿冠状混合器的加力燃烧进行三维两相化学反应流的数值模拟.计算结果表明:相对于环形混合器,锯齿冠状混合器能够显著提高外涵气流的温度和内涵的含氧量,在相同的供油方案下,使得燃烧效率提高14.9%.
Based on computational fluid dynamics（CFD）,the process of three-dimension and two-phase chemical reaction flow of afterburner with confluent mixer and chevron mixer was simulated with introduction of eddy dissipation（ED） model.The results reveal that the temperature of bypass flow and the oxygen content of core flow are enhanced dramatically by chevron mixer,meanwhile,the combustion efficiency increases by 14.9% compared to confluent mixer under the same fuel supply scheme. 更多还原
