摘要

摘要: 为进一步深入研究喷嘴结构参数对气-气掺混燃烧特性的影响,针对氢向氧斜喷带撞击角度的气-气喷嘴开展了实验和数值模拟.实验研究了撞击角度对燃烧效率和燃烧室壁面温度的影响,数值仿真分析了撞击角度对喷注面板和氧喷嘴管壁温的影响.结果表明:随着氢向氧撞击角度的增大,推进剂燃烧效率、燃烧室壁面和氧喷嘴出口管壁面热载降低;氢向氧撞击角度的引入,增大了喷注面板热载.

Abstract: In order to investigate the effect of design parameters of gas-gas injector on mixing and combustion characteristics, experiment and numerical simulation were conducted on the injectors which had an angle that gaseous hydrogen impinge gaseous oxygen. Hot fire tests were carried out to investigate the effect of impinging angle on the combustion efficiency and the chamber wall temperature. Numerical simulation was performed to analysis the effect of the impinging angle on the temperature of the injector faceplate and the oxygen post tip. The results show that the combustion efficiency, the thermal load of the chamber wall and the oxygen post tip decrease as the impinging angle increases; the impinging angle of the gaseous hydrogen towards gaseous oxygen makes the thermal load of the injector faceplate increases.
