| 摘 要： | 应用时空守恒元和解元CE/SE方法,发展了求解化学反应流场的三维并行计算程序。为验证程序,对超声速冲压喷射燃烧室模型进行了计算,计算结果与实测数据以及相关文献的计算结果吻合较好,验证了本文的处理方法和程序的正确性。采用H2和O2的8组分34基元化学反应模型,对不同长深比的凹槽燃烧流动进行了数值模拟,分析了凹槽增强混合对稳定火焰的作用。计算结果表明,CE/SE方法具有模拟凹槽超声速燃烧流动的能力,数值模拟的结果有助于认识凹槽的火焰稳定机理。

| Abstract: | A three-dimensional parallel program based on unstructured grid for reacting flows was developed using the CE/SE method.Firstly,a scramjet combustor model was chosen to validate the present program.The computed results agree well with the experimental data.And then,the cavity combustion flows with three length-to-depth ratios were simulated under stoichiometric conditions by using 8-species,34-elementary reaction model.The flame-holding and mixing enhancement characteristics of the cavities were evaluated.I... |
