HI
I am doing project on simulaton of particle separation in a hydrocyclone,i also have to predict the air core in hydrocyclone ,i am using Eulerian multiphase model and for turbulence i am using standard k-e model in initialization i m giving .2 value in volume fraction of air,my problem is that the air core is not forming plz tell how can the air core can be formed.
