I'm trying to simulate an outlet that is discharging hot air into a larger stream of air represented by an external geometry with a velocity and a pressure boundary condition. I know the temperature and velocity of the unidirectional bulk stream of the external geometry. I also know the geometry of the outlet that is inside of the external geometry (represented by a suppressed solid) , the volumetric flow rate coming out of that outlet, and the temperature of the air discharged from the outlet and injected into the external volume stream. I'm trying to visualize the mixing of the two air streams and the resulting temperature gradient downstream of the outlet.
Is there a way to assign temperature to the air stream leaving the outlet? I understand I can assign temperature and heat flux to the outlet surface. But that looks more like the surface is radiating heat (with some convection) into external volume, I'm looking to find out what happens when I "inject" the heat together with the outlet discharge into external volume. Does anyone know if this is possible to do in Autodesk CFD? If so, what would be the appropriate method of setting the boundary conditions?
