Reaction mechanisms

There are several reaction mechanisms available - all developed and optimised by our team.

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
