ANNOUNCEMENTS

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.

UPCOMING EVENTS

• Fifth International Conference on Combustion Technologies for a Clean Environment, session on Chemical Kinetics, Lisbon, Portugal, July 11-15, 1999; (abstract in pdf format).

RECENT ADDITIONS

• A CSTR option is added to the GRI-Mech Calculator. (November 7, 1996)
• A new version of the GRI-Mech Calculator is released, which has additional options. (July 18, 1996)

• A GRI-Mech Calculator is introduced, which computes interactively ignition of natural gas. (May 1, 1996)

• Reaction Tables are added which display the values and sources of the latest GRI-Mech reaction rate coefficients (February 20, 1996) including now the N-containing species of GRI-Mech 2.11 as well.(April 11, 1996)
• Additional validation tests for a series of low-pressure flames have been performed and the results reported for GRI-Mech 2.11. (February 20, 1996)
• A new series of validation has been performed and the results reported at this Web site: GRI-Mech 1.2 has 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 2.11 replaced GRI-Mech 2.1.
  Dr. Vladimir Zamansky of EER has brought to our attention the following error in the initial release of 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 2.1 were found. (November 21, 1995)
• Tables displaying values and sources of thermodynamic data is expanded to include the N-species of GRI-Mech 2.11. (November 3, 1995)

• Information on the new release, 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)
• Tables are added which display the values and sources of the thermodynamic data of GRI-Mech 1.2. (October 3, 1995)
• The format of the Web Page is modified. It includes various HTML extensions and thus viewed best with Netscape 1.1N or later versions. Among other things, the new format allows to send us e-mail messages directly from the Web page, by clicking on corresponding 'buttons'. (October 3, 1995)
