- 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.
