چکیده انگلیسی
A rotating detonation engine (RDE) combustion chamber fed by hydrogen-air mixtures of different composition was modeled numerically using 3D geometry. The RDE is a new type of engines capable to create higher thrust than the traditional ones based on the combustible mixture deflagration process. The dynamical process of combustion in the RDE is more than 100 times faster than that for the classical slow deflagration combustion mode. This type of engine has a more efficient thermodynamic cycle. In numerical experiments, different combustible mixture compositions were tested, and different scenarios of the engine performance were obtained. The computational domain used a regular mesh of uniform cubic elements. The time-consuming parts of the numerical code were parallelized using the OpenMP technique. Our calculations were made at APK-5 with a peak performance of 5.5 Tera Flops.
