How do you get IPA in non premixed combustion?

  Hello, I am trying to model the combustion of Isopropyl alcohol (C3H8O) and NOx in a combustion chamber and nozzle for a liquid rocket engine. When setting up the non-premixed combustion under the boundary tab and list all the available species, i notice that there is not C3H8O as one of the available species. Is there a way to create a new species or another route i can go down to model this combustion?
  I am also wondering as a side note which model will be the best for modelling this, I am currently using the k-omega model, any suggestions on this as well would be apprecited.

  Hi,
  You can import the required chemistry mechanism in the chemistry tab. K-omega should work.

  Thanks for the reply, I am not sure how to get the chemisty mechanism. Can you guide me to a tutorial i can follow or show me how to create a mechanism and how to import it?
