[blowback]

Hello,

I have a question to you. In your opinion which model of flow will be adequate to use in performing simulation described below?

Flow of water through channel that contains dozens of heated rods - heat flux as a boundary condition on rods surfaces.
Velocity inlet: 0.8m/s - mean value of fully developed velocity profile
Pressure outlet

On the inlet, there are some baffles.

I consider the use of k-omega SST model with Low-Re corrections and curvature correction or k-epsilon standard with enhanched wall treatment.
What do you think about them?

There is boundary layer which consists of 6 inflation layers. Cutcell method was used to create mesh - so boundary layer is the same on all faces beyond inlet and outlet. Whole domain contains ~12 milions of cells.

Thanks in advance for your comments.
