Mixed Convection Inflow BC ??
 
Hello to all here at the forum. I have being using a solver that I implemented and is quite similar to fireFoam. I call it lowMachFOAM. Anyway, I have being able to successfully simulate turbulent free convection boundary layer over a heated vertical flat plate, and I have being trying to feed an inflow velocity at the southern boundary to compute a turbulent mixed convection boundary layer flow. My problem has being with the boundary condition for U and the dynamic pressure. I have to fix the inlet condition for U, but not sure how to handle the dynamic pressure. When I was simulating the free convection part of the research, the BCs were pressureInletOutletVelocity for U and totalPresure for dynamic pressure (pd). Can anyone give me some feedback on how to handle pd at the southern boundary that will ensure stability?? Thanks.

Hi,

I'm sorry i don't have a reply for you. what i have a question. how can i simulate a flat plate in open Foam?

What do you mean by simulate a flat plate? What kind of flow are you solving?

Cheers,
Deji

Hi,

i mean how to create blockMesh file of flat plate?
