Modeling of hydrodynamic cavitation

Hi!
I try to simulate hydrodynamic cavitation in Comsol. The water flows through a constricting device. First, the diameter is 40 mm, then it decreases to 1 mm, then it increases to 40 mm again. The pressure decreases in a narrow section. Therefore, cavitation bubbles are formed.
I used the next interfaces: heat transfer in fluid, phase transport, turbulent flow. But I don't get the correct results. I mean the volume fraction of fluid is the 1, and the volume fraction for dispersed phase (air's bubbles) is 0.
Can someone help me with it? *Sorry for my English.
