Here are the mechanisms which will be detailed in the following section :
They are sorted in decending order of complexity.
This detailed mechanism includes no less than 1034 species and 8453 reactions ...
More information can be found on the dedicated page of the LLNL website.
The Jerzembeck's mechanisms consist of a High Temperature mechanism -which should be sufficient for 1D laminar flame simulations, and a Low Temperature mechanism, comprised of the High Temperature mechanism plus a LT module. These mechanisms were originally derived to model iso-octane and n-heptane mixtures' auto-ignition and burning velocities under a wide range of temperatures, pressures and equivalence ratios; but they are found to properly account for the laminar flame speeds of a variety of other hydrocarbons as well (propane, ethane etc.). More information about the specific range of validity of these mechanisms can be found on this article. The orginal CHEMKIN format can be downloaded from Pitsch's webpage. The CANTERA format (.cti) files can be found here:
- One at low temperature conditions, with 203 species and 1001 reactions,
- The other at high temperature conditions, with 99 species and 601 reactions.
This mechanism is exactly the same as the one used for IFP fuel combustion. Indeed, as far as flame propagation (its velocity and thickness) is concerned, both iso-octane and IFP fuel have the same properties. The only difference is the the auto-ignition delay.
- 1D freely-propagating premixed flame
In order to compute this mechanism with the AVBP transport model you'll need the input files (.dat) from this current directory (the input_species, input_thermo and input_premix files are available).
8 solution files are also available in the directory above for diferent conditions in the range of possible pressure and temperature (they are exactly the same as the ones provided for the IFP fuel combustion with air).
