Default Turbulent flow + VOF

Hi All i'm interested in turbulent flow + VOF + moving object. volume flow rate for my case is ~ 100cm/s. So does anyone have best general guideline on solver settting? my experice with turbulent model is it always limited by explicit viscous solver as current v9.3 doesn't allow implict solver with turbulent flow.

CK,

turbulent viscosity should not limit the time step size since tubulence is only secondary to the mean flow. If it does, it means that turbulence gets out of hand. Make sure you define the turbulent mixing length which should be 7% of the length scale of the main turbulence-producing object in the flow.
