摘要
Abstract
To further study performance of rotating detonation engine(RDE), a reduced kinetic mechanism based on 19-step reaction and 9 species for mixtures of 2H2 +02 +7N2 was used to simulate two-dimensional RDE, and transport processes such as thermal conduction,diffusion and viscosity were ignored. Effects of parameters such as inlet stagnation pressure P0 and back pressure Pl, on performance were studied. Results show that the pressure,temperature and height of detonation wave are affected primarily by inlet stagnation pressure, so are the parameters of outlet plan such as pressure,temperature and velocity. Specific impulse was influenced by ratio of ambient pressure to inlet stagnation pressure.关键词
