Insufficient result in flow velocity profile.

I'm doing simulations with the attached geometry.
Firstly, I should do a fluid flow calculation.
The small center circle is the inlet, and the other (or 2 of 4) are the outlet.
The diameter is same with 6mm.
When the flow rate Q = 0.3 l/min, it shows quite smooth velocity profile.
But when the flow rate is 0.6 l/min and 1.1 l/min, the velocity profiles are not good.
As the Reynolds number at the inlet shows totally the laminar flow, I don't know what I should do.
Any help will be welcomed!
