- 摘要:
- 为了研究液氧甲烷同轴剪切式喷注器结构参数变化对燃烧性能的影响,以单喷嘴为物理模型进行了燃烧数值仿真。研究表明:适当增加氧喷嘴出口壁厚和增加喷嘴个数均能提高喷注器燃烧效率,其中增加喷嘴个数对燃烧效率的影响更为显著。
- Abstract:
- In order to study the influence of structure parameter change of co-axial shear LOX/methane injector on its combustion performance, a single nozzle is taken as a physical model to carry out the combustion numerical simulation. The research shows that the appropriate increase of the wall thickness at outlet of LOX nozzle and addition of the nozzle quantity can improve the combustion efficiency of the injector, and the effect of addition of the nozzle quantity on the combustion efficiency is greater.
