Star or Fluent ?

greg

Hi I want to simulate an expansion tank, so it's a tank with, initially, water and air (free surface). The inlet is only a flow of water for first time ( I want to introduce air bubble later..). So I want to know the quantities of each fluid on the outlet.

So, Wich software between Fluent and Star is the best for this multiphase study?

Thanks in advance

Sorry for my english
