| 摘 要： | 本文在马赫数2.5超燃模型燃烧室中研究与比较了室温、超临界态与热裂解煤油的超声速燃烧特性.针对单路燃料喷注燃料当量比的受制于容易引起边界层分离,从而导致燃烧静压向上游迅速传播跑出隔离段这一问题,以超临界态煤油为例,研究与比较了不同的喷油位置及其组合对燃烧室性能的影响,并讨论了相应的燃烧室性能优化方法.

| Abstract: | Combustion of liquid, supercritical and thermally-cracked kerosene was experimentally investigated and compared in a Mach 2.5 model combustor. It was found that the increase in the fuel flow rate and the pressure rise with the single - staged injection was limited by the upstream propagation of boundary layer separation due to excessive heat release. To solve this problem, experiments with combustion of supercritical kerosene injected at different locations and their combinations were conducted and compared in the Math 2.5 model combustor. Performance optimization of the model combustor has been proposed based on these studies. |
