摘要
采用k-ω两方程湍流模型,火焰面模型和质量加权平均的Navier-Stokes方程组解耦求解的方法,模拟了DLR氢燃料直连式超燃冲压发动机湍流燃烧流场,并与化学反应源项直接采用Arrhenius公式模拟及实验得到的结果进行对比,可以发现湍流脉动对化学反应的影响不能忽略。
A hydrogen fueled scramjet of DLR was numerically simulated by the combination of a k-a, twoequation turbulence model, the flamelet model and Navier-Stokes equations. The numerical results are compared with experimental data and finite-rate reacting model. Computational results show that the interaction of turbulence and combustion in scramjet can＇t be ignored. Applying flamelet to simulate turbulent combustion in scramjet is a good choice.
