Catalytic reforming gas generator is the effective method of producing on-line hydrogen

which is good for the ignition and combustion of hydrocarbon fuel in the scramjet.The combustion and catalytic reforming process were simulated numerically in the new designed gas generator.Based on the agreement between simulated results and experimental data

the parameter variation laws affecting the content of exit gas were concluded.The optimal parameters

the internal combustion characteristic and the content of difficult measured components were obtained.They are a supplement of the experimental results and provide the theory foundation for the design.
