JetA_pPAH_29_277_15_LG ARC mechanism


  • Type of mechanism     :   ARC
  • Fuels used                   :   JetA, C2H4
  • Oxidizer used              :    Air
  • Number of species      :    29 + 15 QSS
  • Number of reactions    :   277
  • Cases of application    :   1D premixed flame


This mechanism has been derived by Lucien Gallen at CERFACS.

It is the combination of HyChem methodology for Jet A from Stanford (Pr. H. Wang) and the C2H4_28_205_14_LG ARC derived from the Bisetti skeletal mechanism from KASUT.

The Mechanism HyChem-KM2 (accessible for Cerfacs members only) used as a detailed mechanism is the HyChem-USCII mechanism with PAHs description derived by Wang

The ARC mechanism can be used for the C2H4 and JetA combustion in air for both atmospheric and high pressure (1 to 20 bars).

Validity has been evaluated for 1D premixed flames on the following range :
P = 1 bar – 20 bar, T = 300 K – 650 K, phi = 0.8 – 2.0.

The ARC mechanism comprises 29 transported species, 15 QSS species, and
277 reactions.
