| 摘 要： | 采用Fluent流场计算软件,对液体亚燃冲压发动机燃烧室的稳态工作过程,包括点火前的冷流场与点火后的两相反应流场进行数值模拟研究。首先,通过二维计算,对比研究两种不同阻塞比燃烧室方案的冷流损失特性与回流区特性,进行方案初选。随后,对选型后方案进行两相反应流场计算,研究燃烧室热态工作过程的温度场、燃油分布与燃烧效率的一般规律,比较并选择适合的燃油供应方案;最后,对燃烧室进行三维详细结构的建模并计算。计算结果很好地揭示了燃烧室内的流动和燃烧过程,与试验数据吻合较好。

| Abstract: | Based on Fluent software,numerical investigation is performed on working process,including non-reacting flow before ignition and two phases reacting flow after ignition,in a liquid ramjet combustion chamber.The inner flow characteristics of two different block-area-ratio schemes are analyzed in total pressure loss and recirculation region distribution.After comparison,the smaller block-area-ratio scheme with good performance is chosen.Then simulation of two phases reacting flow is performed,and temperature ... |
