I'm using Ansys Fluent..
The two pipes in attached geometry figure are intersecting. I want the fluid flow in the main (larger) pipe, to get obstructed by the smaller pipe where it is protruding into it.
The flow from smaller pipe should mix with the main fluid flow from the sides and bottom of larger pipe.
I tried running a simulation, and not getting the desired contour/vectors.
Basically, mixing is not proper, and I suspect it's due to the geometry.
Below are images for what I need:

PS: I tried Boolean, but I think I did something wrong in its application. Really looking for some guidance here for the geometry!

Thank You!

I think the problem here might be that you have to apply some wall thickness to the small part of pipe inside the large pipe.

Thanks a lot for your reply!
So, I should try modeling hollow domain and fill with cavity?
