free Jet Channel
 

Hello,

i model in 2D a free jet in a air-channel.
The nozzle has a width of 1 mm, the channel 50 mm.
The heigth of the channel is 100 mm.
On the fourth side the channel is open.
When i look at the streamlines, the flow is attached to one of the side-walls.
I tried different turbulence models as different pressure velocity coupling as unstaedy flow: result flow attached to one wall.
I heard that during testing there was no attach visible.
(wrong model/wrong test?)

best regards
