Hello.

I am simulating steady, incompressible flow in channel. Dimensions of channel are:
length 6 m, width 350 mm, and height 35 mm.

I did simulations with two RSMs - LRR and SSG. When I compare results of simulations with experimental and DNS data, I see that accuracy of simulations can be improved. Measuring section is at 5.8 m from the inlet.

Figures are on the following links (from some reason, I couldn't attach pictures on this page)

LRR comparison


Here is comparison for SSG simulation:
SSG comparison



I don't have exact DNS data for this case, but I used data for channel flow where Re number is around 40 000 so I believe it can be used for verification, when data are nondimensionalised.

Information about setup are here:

CheckMesh

fvSolution

Any suggestion to improve accuracy of these simulations?

Best regards,
Darko
