H2/O2 oxidation reaction mechanism --
(c) Li, Zhao, Kazakov, and Dryer, Princeton University, 2003.

!!!!!!!!!!!!!!! IMPORTANT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

HOW TO USE THIS MECHANISM:

Due to
(1) limitations of CHEMKIN-II format (specifically, an inability to implement
temperature-dependent collision efficiencies in falloff reactions)
and
(2) lack of fundamental understanding of the mixing rules for the falloff
reactions with the bath gases that have different broadening factors,

the present implementation represents a compromise (approximate) formulation.

As a consequence, PRIOR TO ITS USE IN THE CALCULATIONS, THIS FILE HAS TO BE
MODIFIED. DEPENDING ON WHAT BATH GAS (DILUTANT) IS MOST ABUNDANT IN YOUR SYSTEM
(THE PRESENT CHOICES ARE N2, AR, OR HE), YOU SHOULD UNCOMMENT THE CORRESPONDING
BLOCK FOR THE REACTION H+O2(+M)=HO2(+M), AND COMMENT THE BLOCK FOR OTHER DILUTANT(S).
AS GIVEN, THE MAIN DILUTANT IS SET TO BE N2.


HOW TO REFERENCE THIS MECHANISM:

of Hydrogen Combustion", Int. J. Chem. Kinet. 2004 (in press).

**********************************************************************************************
Development notes:

The following H2/O2 mechanism is based on Mueller et al's (Int.J.Chem.Kinet.1999,31:113)
Changes:

1.update the standard heat of formation of OH at 0K to 8.85kcal/mol (Ruscic et al,
J. Phys. Chem. A, 2002, 106:2727)

2.update the rate constant of H+O2=O+OH as proposed by Hessler (J. Phys. Chem. A, 1998,
102:4517)

3.update the low-pressure-limit rate constant of H+O2(+M)=HO2(+M) with bath gases: H2,
O2, N2, AR, HE, H2O as proposed by Michael et al (J. Phys. Chem. A, 2002,106:5297).
The third-body efficiency of H2, O2, and H2O are taken as the average value over
the temperature range of 300-3000K.
The Fc in Troe's form with N2 and AR/HE as bath gas are different, so the fall-off
kinetics is expressed in two sets, for N2 and AR/HE, respectively.

4.for all other recombination reactions, assume the third-body efficiency of HE is
the same as AR.

5.modify the A factor of the rate constant of H+OH+M=H2O+M to 3.8E+22.
