Good day all. I'm sorry if it has been posted before, but I was wondering which are the best solvers and turbulence models(realizable, RNG??) to apply when trying to understand the air distribution in a room.

The room dimensions are 5.5 X 3.7 X 2.4 m (Length X Breadth X Height). Air is introduced at the right side of the diagram, and air is leaving on the left side. My project requires me to try to replicate the experimental results using CFD (FLUENT), which I am very new to it.

I took the cross section at exactly the mid breadth of the room to plot the velocity vectors. Here are my results for experimental and CFD (my work) in the attachments.

I have done such work before. k- ω for turbulence!
You should model the external flow as well. Increase grid density!
