Hi...I'm trying to simulate one part of the wind tunnel body(vacant body w/out screen and honeycomb)..from the settling chamber > contraction > test section...What should I put in the solver (convergence control and equation class setting).In fact..I want to get 80 m/s in the test section.what kind of turbulence model and requirement should be taken....Thanx

Hi,

Turbulence model - SST should be good here. If you are interested in the development and/or transition of the boundary layer on the tunnel walls then consider the transition model.

Should be a straight forward simulation.
