Results of experimental studies on a H2/air continuous rotating detonation engine (CRDE) in an annular combustor are presented. A tangentially injected H2/O2 hotshot jet is used to ignite the engine. detonations realized at wide range total mass flow and equivalence ratio conditions. The propagation modes all tests can be divided into four kinds: two-wave, hybrid two/one wave, one-wave, transient one wave. mean velocities two-wave one-wave 1365–1476 m/s 1606–1791 m/s, respectively. mode...
Characteristics of continuous rotating detonation (CRD) in a cavity-based annular combustor are studied through three-dimensional simulations, which solved OpenFOAM with skeletal chemical kinetics mechanism. The results show that the wave (CRDW) attaches to outer wall and detaches from inner combustor. A high-temperature recirculation zone is found cavity reactive intermediate species identified as ignition source, provides heat active radicals enhancing detonability combustible gases front...
The spark ignition and flame stabilization of kerosene in a dual-cavity scramjet combustor is investigated with the isolator entrance Mach number 2.52, total pressure 1.6 MPa, stagnation temperature 1486 K, which corresponds to flight condition. effects configuration on flameholding were analyzed. Two distinct cavity-organized regimes found: cavity shear-layer flame. driving force transition mode from high resulted combustion, occurs cavity. scheme can promote ability. First, downstream...
In this short letter, simultaneous high-speed schlieren and chemiluminescence imaging is demonstrated in a rounded-rectangle continuous rotating detonation combustor for the first time. Typical flowfield structures of (CRD), such as fuel injection structure, fresh combustible mixture layer, wave, downstream oblique shock are clearly identified by images. Integral intensity (ICI) images fluctuates periodically, indicating rotation motion wave reaction zone, propagation frequency CRD can be...
Three-dimensional numerical simulations with detailed chemistry were conducted on a rotating detonation ramjet engine (RDRE) fueled by ethylene. The study compared the basic structure, combustion characteristics, and performance of wave (RDW) between isometric divergent combustors varying angles. results reveal that RDW propagates slight inclination relative to circumferential direction in combustor, whereas it larger combustor. resultant velocity perpendicular combustor exceeds remains...
