Dear Foamers
I am doing a simple problem of pipe flow simulation for a wedge shaped domain with WEDGE boundaries at the two axisymmetric sides. I have a dead zone near the inlet where recirculation bubbles formed.The problem is, even I have laminar flow, the inlet jet doesnot break and the bubble is just stretched with flow. I am also not getting parabolic profile at the downstream (due to the bubble stretching may be). I am using laminarSimpleSMOKE solver, which is nothing but the PisoFOAM with chemical reactions.
Do anyone of you faced similar or related problem? Any kind of suggestion or solution is highly appreciated for you.
