What is the Best CFD Software for Modeling Heat Flow from a Jet Engine Exhaust?

[TJ_Laser]

Hi guys this is my first post. I hope it's in the right place.

I am trying to model heat flow over a plate positioned very close to exhaust from a jet engine. Can anyone recommend software that can do this? I'd like to be able to visualize the airflow itself, its temperature and the temperature gradient of the plate where it contacts the airflow.

Try Ansys-Fluent module. hope this helps you

Any of the big ones will be fine (Ansys Fluent or CFX, Star, etc). If you want to do a full conjugate heat transfer model, then you'll probably need a heat transfer and multiphysics license.

What's important in this problem are your boundary conditions. Are you assuming a uniform exit profile from the jet nozzle? Do you have an experimental or numerical profile? Temperature can vary quite a bit coming out of the turbine.

Ansys looks promising. I will look into it.

We don't yet know the full scope of this project and the boundary conditions are not well established. I believe the gas flow will be simplified from experimental data. I think it's safe to say the exit profile is uniform but I'd like the freedom to model something more complicated should the need arise.

Thanks for the helpful replies.

Follow up: Solidworks Flow Simulation is doing the trick beautifully.

Be careful with that package. It is not intended for any complex, serious CFD modeling. I would certainly certainly NOT pull heat convection BCs out of it. You may be decent on a pressure drop, but it will be very hard to get a proper thermal boundary layer.

Oh really? I didn't realize that. Maybe I'll keep looking then.
