Hi to all,

 

I'm new in here and I need help. I've spent a lot of time trying to find an answer to my problem, but I still haven't found one, so this forum is my last hope. Any help will be highly appreciated.

 

Problem

 

I've got a pipe which should take an external air flow simulation test (simulating pipe in the wind tunnel). The problem is that the air flow is not going inside of the pipe, or if it goes than it is like 3-5 pipes out of 1000. I know that it deffenetly has some airflow inside, as I've done the test in the scale wind tunnel. I'm adding a screenshot, hoping that it will explain problem better.

My flow conditions are inlet z = -10m/s at standart atmospheric pressure. Thank you for all the answers in advance.
