Default VOF & Species bubbles

Hi, i am modeling a multiphase flow in a tank with vof. The tank contains half of water and half of air (free surface). On inlet (VI) there is only water, and my calculation give me good results. But now i want to add (small) air bubbles on inlet. I have seen that only vof can't do this and DPM is not either the solution. So, i try to use species transportation model but i am novice in. i want that bubble are in the same air that in the tank, and i have no thermal or chemical reaction.

Someone can help me to do this? very veru thanks

best regards, Greg
