【摘要】 对取样探针内的流场进行了一维分析,证明气流中的化学反应能够被成功冻结。建立了取样分析系统,并对其进行了密封性校核。利用该系统对燃烧室尾气进行了取样以及色谱成分分析,进而推算了燃烧效率,得到的结果与实验观察以及燃烧室壁面静压测量结果相吻合。更多还原

【Abstract】 It was proved that the chemical reaction of the flow in the sampling probe was quenched by the analysis of 1-D.A gas sampling/chromatography analysis system had been established and it was checked for vacuum packaging.The system was used to sample and analyze the exhaust of scramjet.The combustion efficiency was acquired through the experimental results,which were agreed with the observation and the measurement results of static pressure on the combustor wall.更多还原
