| 摘 要： | 本文用κ-ε湍流模型和液雾轨道模型,对二维内外函混合加力燃烧室扩压器内有蒸发的液雾两相流动和混合进行了数值预报。其中对气相速度场和温度场的计算结果与实验符合令人满意,液雾两相流的计算结果在趋势上也是合理的,表明本文的模拟方法可用于加力燃烧室性能估算及优化设计。

| Abstract: | The k-ε turbulence model and particle trajectory model are used to simulate the turbulent two-phase flows and their mixing in a diffuser of afterburner. Predicted velocity and temperature distributions for single-phase flows are in good agreement with experiments. Two-phase flow and concentration predictions give plausible results. Hence, the proposed model is feasible for further applications in combustion performance predictions. |
