brundon New Member Andrew Join Date: Mar 2011 Posts: 1 Rep Power: 0	I am running a two-phase simulation with water and air in round ducts of 20 mm diameter. I am using the Mixture method and the simulation seems to converge. However, upon close inspection of the phase fractions, the air fraction seems to yield a homogenous distribution in horizontal pipes. This is not realistic as most bubbles are expected to rise to the surface. Any suggestions please??
