Is it feasible to use Ansys Fluent for the simulation of a ramjet's internal combustion flow? It would be a density based supersonic compressible simulation and I'd have to simulate the mixing of iso-octane fuel in the ramjet.

What would be the limitations? I'm trying to stick with Ansys Fluent so I can avoid OpenFoam.

limitations come from model which you are going to use for simulation

What would the ideal models be for this case? I've been using energy equation on and k-omega SST for simulating a supersonic wind tunnel. Except that simulation need to have combustion.

That "except" is actually the tricky part. I suggest you should have a look around the internet and see what other people did. There are many papers of people using ansys fluent to do scramjet CFD. Have a look. However, I have the feeling that most of the models are intended for subsonic combustion, so I am not sure about the accuracy of those at such exotic combustion conditions.

Try to assess both if the models are able to give you accurate solutions or qualitatively accurate solutions. The first one is self explanatory, but I am not sure if Fluent has such capability. With the second one I mean that, maybe the absolute values are not 100% correct but you are able to qualitatively predict changes in flame temperature, shape ecc as a function of variables such as chamber pressure, initial flow temperature ecc
