Hello Everyone

I've been searching for the solution of this problem for two days
but cannot find the answer.

I'm simulating the inline mixer. It is used to mix two liquids
(liquid in the small pipe, and liquid in the big pipe) as you see in the picture.

The results from CFX shows that the velocity of the liquid in the small pipe after
flowing out the small pipe distributes all over the inline mixer but when I ran the same condition in order to transfer the model to Fluent code (same geometry, meshing, and boundary conditions)

The velocity profile obtained from Fluent is really different from the CFX as you see in the picture.

Could you suggest me to solve this enigmatic problem?

Thank a lot in advance.

PS1. I used mixture model in Fluent.
