Numerical Investigation on the Effect of Fuel-Rich Degree in the RBCC Engine under the Ejector Mode by Yizhi Yao, Mingbo Sun, Menglei Li, Peibo Li, An Bin, Rui Gu, Jiaoru Wang, Feng Wei, Taiyu Wang, Jikai Chen

“…However, it improves the overall performance (Isp) at high flight Mach numbers (Maf). For supersonic conditions, increasing the fuel-rich degree promotes greater fuel participation in combustion, thereby enhancing RBCC engine performance. …”
