Default twoPhaseEulerFoam: air is created at edges

Hi all,

I'm doing a simulation using twoPhaseEulerFoam with an air injection in water (see tutorial injection). I'm using the mixtureKEpsilon model for turbulence, using the same boundary conditons as the other RAS tutorials.

I have a problem at edges where boundary layers start to develop, since air (alpha1) is created at these edges. without fvOptions only small quantities of air appear, while with an air mass source this problem is enhanced.

I have the same problem in laminar flow. I also tried different div schemes without changes. Any suggestions?

Thanks (I'll send the input in private if needed).
