Good night for all,

I'm posting this message because I already tryied everything that I could but nothing worked. I'm sorry for the errors that I might do in english.

Well, I'm trying to simulate a bubble inside a wind tunnel generated by an adverse to favorable pressure gradient driven flow. I have attached a picture of the wind tunnel so it will help you to visualize the whole process.

I have just two known experimental boundary conditions: 25 m/s the flow velocity at the inlet and turbulence intensity of 0,003 (it's really low). At the outlet I'm setting opening, zero relative pressure and Default Intensity and Autocompute Length Scale. At the suction part, the same as at the outlet and no-slip for the wall.

I used two different turbulence models: k-epsilon and SST Menter. I know the first one is not good to predict well the location of separation and also the amount of separated flow. I used it just for comparison purposes.

For some reason that I don't know, the flow is not symmetric. I was not expecting to see something completely symmetric, but neither to see this flow skewness at the upper wall.

Could you please help me?

Thanks.

Matheus
