COMSOL Limitations with Turbulent Two phase flow?

Hi,

I am working on a problem pertaining injectors. I am using the Fluid flow physics module and in particular the Turbulent two phase module. I have gone through the benchmark models and tutorials available in COMSOL 4.4. All of them use laminar two phase flow. I would like to know if there are any limitations in turbulent two phase flow analysis for high velocity in COMSOL 4.4

Can someone please comment on this.

Many thanks
