[ANSYS Meshing] Creating a heated zone

erica_p · July 9, 2014, 00:19

Hi guys,

I am new to CFD, and spent the last one month trying to learn the basics. I am trying to simulate a flow in a closed chamber, where the air is heated by a couple of heating coils. As a first approximation, I just created a thin fluid zone and added an energy source to it in FLUENT (since I did not want to simulate a conjugate heat transfer problem right away with the actual heating coils). However, I am concerned about the fact that since this is a different zone, it is meshed differently than the rest of the fluid domain. My question is: is there a way to have it meshed in the same way as the rest of the fluid domain, and yet be able to 'heat' it up as a separate zone? Sorry if this is elementary, but I couldn't really find an answer on this forum!!

Thanks,

Erica

If you are meshing it in Ansys Meshing you have to create one part from all of your domains (Ansys DM -> Geometry -> Pick all parts -> Form New Part) and then it will be meshed as a one part and it will be "separated". If you do not want to create a part from your domains or your're using another mesher you can create Interfaces from walls of your domains which are coincident and then the mass flow through these walls will be modeled by Fluent.
