摘要:
采用nucnt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 ale 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 field，fuel distribution and combustion efficiency are obtained， which helps to decide a reasonable fuel feeding scheme．At last，the results of three dimensional simulation provide a more particular understanding of flow and combustion process，and simulation results fit the experiment data well．
