摘要：ANSYS FLUENT 14 supplied the CFD tools used in the numerical calculation of rotating detonation combustion. During calculations, various fuel injection methods and configurations of combustion chamber were applied in an attempt to obtain stable and correct detonation propagation results in a separated fuel-air injection system (non-premixed combustion model). However, FLUENT was not originally designed for detonation combustion and the failure to achieve re-initiation of detonation after collision was always the core issue in the non-premixed combustion model. Thus, this paper mainly focuses on research into the behavior of stable continuously rotating detonation in premixed combustion cases. The analysis of stable continuously rotating detonation behaviors and structures was carried out with different boundary conditions and mesh cells. The pressures were measured by using a number of artificial sensors inserted near the chamber outside surface in various axial and/or circumferential directions. With those key results in the case of premixed combustion, we were able to comparably conclude that stable rotating detonation would also be generated if the refilling process were properly exhibited in non-premixed combustion. The paper finishes with evaluations and conclusions regarding general detonation behaviors and performances.
