【摘要】 对公开发表的用于超声速燃烧流场分析的几种一维模型进行了研究,指出了其中存在的问题。研究结果表明:基于实验静压数据的一维模型,若不借助必要的流场测量数据或分析结果,或借助于经验性的处理方法,单靠一维假设,无法获得较为完整的一维流场分析结果。改进后的一维模型降低了数据处理过程中的不确定性,提高了对一般情况的适应能力。用编制的计算程序SSC-2对两组典型的超燃燃烧室壁面静压实验数据进行了演算,取得了燃烧室出口总压恢复系数的计算值与测量值基本一致的好结果。更多还原

【Abstract】 The existent one-dimensional flow analysis models for supersonic combustor were studied. The results showed that the complete solution of one-dimensional combustion flow field could only be obtained with either necessary experimental data or some empirical methods. With the improved model, the uncertainty in the process of data reduction could be reduced. The adaptability of the code could be enhanced. The calculated values of static and stagnation pressure showed good agreement with experimental data.更多还原
