multiphase flow in Star CCM+

Sorry for my english)

I am modeling the flow in an open channel with the free surface (Eulerian Multiphase). I have some problems in an inlet zone. The flow of air creates vortices, which creates waves on the free surface. It is unphysical. The inlet velocity of air = 0m/s, the inlet velosity of water = 0,17m/s. It should be noted this does not occur at higher speeds. Maybe someone encountered a similar problem and knows how to get rid of these vortices at the inlet.

Thanks in advance!:)
