mass flux in two phase flow
 

hi dear foamer
im using interFoam to calculate a two phase flow in axisymetric mesh with cyclic boundary.
now i like to calculate mass flux for gas and liquid but i dont know how? :(
My difficulties are :
1) patch are cyclic in cyclic patch mass transfer is zero!
2) i like to know the mass flow rate of gas and liquid individually

comment plz?
