What are the most common value to use for the turbulent intensity and length scale when using K-e model in a cleanroom air flow. The air speed is at 0.4m/s. Doesn't is need to set up the gravity too. It is running in 2-dimension and the height is at about 3m and width at 4.6m.What boundary codition should I be using, currently I am using velocity-inlet as my inlet and pressure-outlet as my outlet. My outlet length is about 0.28m and inlet at 1.5m, and it is located at left hand corner of the ceiling and right hand corner of the ceiling respectively. The flow should be a u-shape. But my data in the fluent for the velocity do not match with the physical experiment data. Please tell my problems. Need help desperately. I am working on my final year project.

No, I think it`s not necessary to set up gravity. Elena
