Numerical study on the combustion characteristics of afterburner with chevron mixer
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.
