AbstractJapan Aerospace Exploration Agency has been investigating scramjet engines in Kakuda Space Center using RamJet Engine Test Facility (RJTF) et al. The engine tested at the flight condition of Mach 6 showed very steep fuel distribution. The fuel injected from the vertical injector on the side wall stays near the side wall and the tap wall along the engine. The steep fuel distribution is an obstacle for the engine performance completion. In order to solve the problem, the authors are focusing the influence of cowl shock wave on the fuel distribution. In this paper the authors describe results of combustion calculation in the engine and discuss how the combustion calculation simulates the real engine combustion flow field. Fair agreement is obtained in pressure distribution, but thrust performances do not yet agree well.
