Hello,

I am working on a Combustion-Chamber-Nozzle Rocket Engine design and using ANSYS Fluent to simulate the flow of the mixture.

I want to use a Mechanism for a Liquid Methane, Liquid Oxygen Combustion.  The closest I found was a 2-step Methane/Air mixture but I want something that is more based on previous research

In the ANSYS Fluent Software I have successfully created a geometry and a mesh. I currently am working in the Setup.

Under Setup > Model > Species  there is the menu to select the type of mixture material. I am going with a standard species transport. I want to use a liquid oxygen, liquid methane combustion mechanism mechanism that I found in a previous research. My challenge is to figure out how to actually create a version of it that i can then upload to the program.

Attached below are pictures of the menu in ANSYS Fluent Species and

a picture of the reduced 7-step mechanism I want to use.

Could somebody guide me through the steps to upload this mechanism into ANSYS Fluent? I am only a few weeks new to the software and have limited experience. Any help will be muchly appreciated after having spent days trying to figure it out. Thank you!

I would suggest building up to this slowly. Methane+air is a good starting point. For LOX & liquid methane you may also need a multiphase model, that't not going to be a straightforward model.

So any suggestions on where to begin?
