Reaction mechanisms



DLR Concise
Version 1, 2021, Jet fuels (DLRConcise2021v1.JF)

A compact reaction mechanism for H/C/O neat components and fuel surrogates

  • A single semi-detailed reaction mechanism enables modeling combustion chemistry of spectrum of real fuels represented through surrogate fuels
  • Customized reduction possible for CFD applications

Chemiluminescence (ChemLum2012)

A reaction mechanism for prediction of OH*, CH* and C2* chemiluminescent species

  • Detection of non-intrusive OH*, CH* and C2* species is frequently used in the diagnostics
  • A reaction model of such species enables direct comparison to their measurements in various combustion environments
  • Mechanism supplied with the C1-C4 chemistry from 2012, however independent use of only chemiluminescence chemistry possible
