Abstract
The rotating detonation engine is a promising realization of pressure gain combustion
for propulsion and power generation systems. A rotating detonation engine running
on ethylene-oxygen is simulated by using AMROC with a second-order accurate finite
volume method and approximate Riemann solvers. Multi-step chemical kinetic
mechanisms are employed with a splitting approach. The rotating detonation is studied
in a 2-D unwrapped chamber with premixed and non-premixed injections and is
then simulated in a 3-D annular chamber. The results show that using the adaptive
mesh refinement method can simulate rotating detonation problems efficiently.
