| 摘 要： | 基于正交设计研究了各设计参数对富氢/富氧燃气气-气多喷嘴推力室燃烧位置、壁面温度及喷注面板温度的影响趋势和影响程度.方差分析和极差分析结果表明：燃氧速度比是影响燃烧长度和壁面温度的主要因素,较小的氧喷嘴出口厚度有利于降低喷注面板温度,但各因素的交互作用对不同设计目标影响程度差异较大;多目标响应面分析表明：低的氧喷嘴压降...

| Abstract: | Orthogonal design methodology was applied to investigate the design parameters' impact on multi-objectives,including flame length,wall temperature and injector panel temperature of GH2/GO2 fired gas shear coaxial multi-injectors chamber.Variance analysis and range analysis indicate that ratio of hydrogen-rich gas velocity to oxygen-rich gas is a dominant factor for flame length and wall temperature,and small thickness of injector is beneficial for reducing injector panel temperature.The interaction effect of the design parameters varies sharply for different objectives.The result of response surface shows that low pressure drop of oxygen-rich gas,high velocity ratio and appropriate injector thickness are advantageous for balance performance. |
