GRI-Mech, we are continuously updating and expanding this Web site. If you noted any typos, errors, or have a suggestion regarding the Web site or the
GRI-Mechitself, please let us know. We list such questions and comments along with our replies in BUGFIX file. The spotted typos and errors of a more serious nature are also addressed in Recent Additions below.
While the new GRI-Mech releases will be announced, the many extensions and additions to the Web page itself will remain 'silent'. You may, however, quickly check on the recent and upcoming additions to the page by periodically browsing through the information given below.
GRI-Mechreaction rate coefficients (February 20, 1996) including now the N-containing species of
GRI-Mech 2.11as well.(April 11, 1996)
GRI-Mech 2.11. (February 20, 1996)
GRI-Mech 1.2has been compared with new shock-tube measurements of OH profilies in high-pressure methane ignition from Stanford University (Petersen, Davidson, Rohrig, Hanson and Bowman). (December 18, 1995)
GRI-Mech 2.1. The 'E' terms in the rate constant expressions for reactions (277) NH3 + H = NH2 + H2 and (278) NH3 + OH = NH2 + H2O should be positive rather than negative as originally given. The mechanism file has been corrected as of November 4, 1995, and the corrected version is referred to as
GRI-Mech 2.11. This change does not affect our results because the mechanism was not designed for ammonia or deNOx kinetics, and none of the targets chosen for the 2.1 version or validation experiments tested afterwards show measurable sensitivity to these reactions. Recalculations of all targets and validation experiments has been done with
GRI-Mech 2.11. No significant changes from the results obtained using
GRI-Mech 2.1were found. (November 21, 1995)
GRI-Mech 2.11. (November 3, 1995)
GRI-Mech 2.1, is added, which includes discription of the optimization targets chosen, sensitivity diagrams computed for these targets, and results of the validation tests performed. (October 3, 1995)
GRI-Mech 1.2. (October 3, 1995)
