Hi all, good morning.
I am using simplefoam(v1.4) to calculate a swirling flow in chamber, the case is download from ERCOFTAC database.

It is a 2D case.

But I got some problem.
When I want to compare the results with FLUENT ones, it seems that the result from FOAM have a great "dissipation".
i post the velocity magnitude here, you may find that the high velocity in FLUENT last long.

I used realizable k epsilon model for both of them.
The grids are the same, y plus are around 60. (before this case, I run a case which y plus are around 5, the same thing happened.)
Both of them use the same velocity inlet.
the numerical schemes i used default ones, cause i confused by the differences between FOAM and FLUENT.

Please, give me your ideas.
Thanks.
