Hello,
I am attempting to model combustion in a combustor using a fuel (A1) that is not present in the ANSYS material library.

The Nasa Polynomials of this fuel has been determined by a report listed at the website here. The fuels transport properties (dynamic viscosity and thermal conductivity) can be assumed to be similar to Jet-A and the thermodynamic state is set as a gas to reduce complexities.

The combustion model being used is an eddy dissipation model with the k-epsilon turbulence model and total energy heat transfer model.

In order to obtain more accurate results, I am attempting to use a chemical reaction file called the HyChem. A link to this website with downloadable files can be found here. As seen from the website, it is in a text file format, and ANSYS Reactions do not allow text files, nor is the original HyChem txt file in the proper format in any regards.

I have attempted using the Jet-A chemical reaction, but this does not accurately model experiment results. I have investigated how other researchers use different fuels in combustion simulations, but none of them use CFX as the software.

If there is anyone with experience/guidance on the best way to use these reactions in the CFX library, I would really appreciate the guidance. Thank you all very much!
