CH4_13_73_4_LU (Lu13) ARC mechanism


  • Type of mechanism     :  ARC
  • Fuels used                     :  Methane
  • Oxidizer used                 : Air
  • Number of species      :  13 + 4 QSS
  • Number of reactions    :  73
  • Cases of application    :  0D, 1D


This mechanism has been derived by Ramanan Sankaran in the Combustion Research Facility at Sandia National Laboratories.

It is derived from a 17 species skeletal mechanism itself derived from the GRI-mech 1.2.

It comprises 13 transported species, 4 QSS species and 73 reactions.

This mechanism is advised by the authors to be used only for flame speed calculations.

NB: The original fortran file was using CGS unit system (Chemkin) for the production rates computation; corrections have been made for it to work in SI unit system (with kmol instead of mol in Cantera). A comment indicates those modifications within the file.
