Hello,
I am trying to model a square geometry with air inside and the walls at fixed temperatures. The model I chose was this:
Conjugate Heat Transfer --> Turbulent Flow --> k-e model using stationary.
I built the square easily enough.
For Materials, I choose air at an average of 50C. From there, I took the properties I needed:
Thermal conductivity, density, Cp, dynamic viscosity, and ratio of specific heats.
I applied boundary conditions to the square for the temperature. I made the top and bottom insulated. The right side of the box is at 0C and the left side is at 100C. These are boundary conditions.
My question is this: I made a normal mesh and tried running it but it just doesnt go anywhere. The mesh only has 3000 element and 12,000 dof's. I have done more on my computer so I know it can handle it.
Do I need to apply some sort of conditions for the turbulent part?
I'm just trying to get the walls to heat the flow and look at the fluids movement.
Thanks,
David
