ASSESSMENT OF TABULATED CHEMISTRY MODELS FOR THE LES OF A MODEL AERO-ENGINE COMBUSTOR

open access: yesProceedings of Global Power & Propulsion Society, 2022
Tabulated chemistry methods present a compromise between computational cost and the ability to capture complex combustion physics in high-fidelity numerical simulations. The application of such models entails a number of modeling decisions, that may affect the simulation results significantly, especially in partially premixed combustion, where the ...

Detection of the hydroperoxyl radical HO2 toward \rho Oph A: Additional constraints on the water chemical network [PDF]

open access: yes, 2012
Context: Hydrogen peroxide (HOOH) was recently detected toward \rho Oph A. Subsequent astrochemical modeling that included reactions in the gas phase and on the surface of dust grains was able to explain the observed abundance, and highlighted the ...

A universal chemical potential for sulfur vapours [PDF]

open access: yes, 2015
The unusual chemistry of sulfur is illustrated by the tendency for catenation. Sulfur forms a range of open and closed S$_n$ species in the gas phase, which has led to speculation on the composition of sulfur vapours as a function of temperature and ...
