Help with Jet Simulation

Help Desk amjaiin writes " Hi all,

I am a new user in Fluent. I want to simulate a vertical water jet in 2D in the presence of gravity and air. For this I made the geometry as such: a rectangle grid with the bottom edge as a wall and side edges as pressure outlets. The upper edge is also a pressure outlet except for a small edge, representing the jet, which is a velocity inlet. Will this configuration work?

In fluent, I am using the k-eplison model with the gravity option and the operating media as air.

But when I am simulate the jet using this model, I don't get the result I expect (it gives some upward motion after few cms).

Please suggest some changes I should make to correct the model.

Thanks,
Amit"
