“…The development of detailed kinetic models to predict the pyrolysis and oxidation properties of various fuels has received significant attention over the past number of decades. This is due to the need for reliable kinetic models for use in the rational design of practical combustors. − Owing to the hierarchical nature of combustion chemistry, the core kinetic models usually recognized as the models for C 0 –C 3 /C 4 hydrocarbons are not only of the utmost importance in understanding the combustion properties of the small components themselves but are also the foundation for the development of kinetic models of real fuels. The first universally successful attempt to develop such a kinetic model for natural gas combustion was probably GRI-Mech, which was involuntary adopted as a core mechanism.…”

Core combustion kinetic mechanisms for small C 0 −C 4 fuel molecules are not only of the utmost importance in understanding their individual combustion properties but are also the foundation for the development of kinetic models of real fuels. This brief communication intends to develop efficient skeletal core combustion mechanisms for the oxidation of C 0 −C 3 /C 4 fuels using the recently developed NUIGMech1.1 as the detailed mechanism. A combination of different skeletal mechanism reduction methods is employed to produce two skeletal mechanisms for C 0 −C 3 and C 0 −C 4 fuels, separately. The skeletal mechanisms have been validated by comparing against a wide range of combustion targets, and the maximum error in ignition delay time predictions is less than 10% for all of the targeted fuels. The C 0 −C 3 skeletal mechanism is also employed as the core mechanism in the development of a five-component skeletal mechanism for real gasoline. The developed skeletal mechanisms should represent a valuable resource for mechanism development and kinetic modeling within the combustion community.

“…The construction of a reasonable physical model and chemical kinetic mechanism of aviation and aerospace fuels will help researchers to deepen their understanding of the pyrolysis and combustion process of aerospace fuel, and then play a guiding role in engine design and optimization. Researchers have proposed a large number of physical replacement models [1][2][3] and related chemical mechanisms for aviation fuel through experimental studies. 4,5 These studies enable people to understand the thermophysical and thermochemical properties of aviation fuel, but there is still a lack of details about the fuel reaction path and free radicals in the combustion process.…”

“…ost of current air-breathing scramjets are designed to operate in the Mach number (Ma) range of 4-8, because of the near-term military demands [1]. However, scramjets designed to operate in Mach numbers above 10 are urgently needed to meet the long-term demands from earth-to-orbit-and-return transportation systems, possibly by using a hybrid launcher combining scramjets inline with other propulsion technologies, e.g., rocket [2].…”

Internal-external coupled full-scale modeling for a rectangular-to-elliptical shapetransition (REST) scramjet under a high flight Mach number of 12 was modeled by Improved Delayed Improved Delayed Detached Eddy Simulation (IDDES) and a Dynamic Zone Flamelet combustion Model (DZFM). The modeling is based on a total cell number of 63.03 million and a 13s/33r nonequilibrium hydrogen mechanism. The effect of differential diffusion was investigated for the flow fields, efficiency indices, and thrust performance. A sensitivity analysis of the zone discretion was conducted to select the optimal zone number with acceptable accuracy yet high efficiency. The predicted wall pressure is comparable with the measurements. Detailed analysis of the characteristics of hypersonic flow, reacting species, and combustion was analyzed by using Takeno Flame Index (TFI) and Chemical Explosives Mode Analysis (CEMA), etc.
