How to calculate mass flow of the discrete phase in Euler-lagrange model
 

Dear Friends, I am using ANSYS CFX for simulating an oil gas separator (vertical.gravitational). I am using the Euler Lagrange model since the volume fraction of the dispersed phase is less than 10%. BUT I can not determine the mass flow of the dispersed phase in any outlet., because in the E-L model the dispersed phase is simulating as particles.
Do anyone know hot to determine that mass flow???
