To calulate the adiabatic flame temperature using Cantera, we need to provide a .cti file that stores all thermodynamic information needed. We can simply convert a Chemkin mechanism file to .cti file like Gri3.0 to calculate the adiabatic temperature of CH4/Air for example.
However, how can we generate a .cti file containing thermo-properties of not only gases but also some solid substances like Al and Fe to calculate adiabatic temperature of Al/Air and Fe/Air dust flames ?
Hi Daoguan,
I'm also interested in exploring how to use Cantera to calculate equilibrium state for a heterogeneous metal-fuel mixture. Although I haven't tried this before, I guess that we can define solid fuel and its condensed-phase products as "stoichiometric_solid()" in CTI file. The thermodynamic data of Al, Fe, and their oxides are available in the JANAF database and their corresponding polynomial fitting (Shomate equation) can be found in NIST Chemistry WebBook, for example, data for Fe:

Hi Xiaocheng, Xiaocheng Mi
Thank you for your suggenstion.
I solved it by following one example called "plasma_equilibrium" posted at Cantera website.
I replaced condensed phased by what are needed and added the thermodynamic data of few species into the 'nasacondensed.cti' file that is already available in the installed cantera folder but is not completed.
The thermodynamic data are generated by NASA thermal build web application, which are 9 coefficients instead of old 7 coefficients.
