Default Velocity Profile
Posts: n/a

I am trying look at the velocity profile for a ball valve that I am modeling. My solution converges using the Reynolds Stress equation with a velocity input and a pressure output. I know that there is some sort of turbulence going on inside the ball valve, but when I look at the velocity profile I am getting a uniform velocity profile throughout the whole valve until the output. This does not make any sense to me. Any suggestions?

Even if you are seeing uniform velocity profile, turbulence emay be present.

So look for turbulent quantities such as k and turb. intensity.

The time-men uniform filed may contain turbulence which is averaged out.
