Chemkin
New functionality to use Real Gas Property (RGP) table with Batch reactor and Plug Flow reactor models.
Added user-defined collision kernel in the sectional method for Batch reactor, Plug Flow reactor, Premixed flame reactors, and Opposed Fow reactors.
Added dark mode option for User Interface display.
Added option to estimate Exhaust Gas Residual (EGR) composition in Premixed flame models.
Added option to estimate liquid density in Multiphase models.
Reaction Workbench
New utility for converting thermodynamic data from standard format to NASA9 format.
New utility for converting duplicate PLOG reaction rates to single aggregate reaction.
Added option to retain nitrogen species when extracting submechanism by removing nitrogen-containing species.
Added option to use the InChI species identifier in addition to SMILES during mechanism merge.
Model Fuel Library
All MFL mechanisms have been updated. Improvements include:
Added gas-Phase autoignition chemistry of ethylene carbonate and dimethyl carbonate, which introduces options for modeling lithium-ion battery thermal runaway.
Improved NOx and soot surface chemistry.
New pre-reduced MFL mechanisms for conventional and carbon-neutral fuels that incorporate the changes to the full mechanisms:
Mechanisms for hydrogen, ammonia, natural gas, propane, methanol, ethanol, gasoline, diesel, jet fuel, and sustainable aviation fuel.
