15.12.4 Mass Exchange

The mass transfer from the discrete phase to the continuous phase is computed in ANSYS FLUENT by examining the change in mass of a particle as it passes through each control volume in the ANSYS FLUENT model. The mass change is computed simply as

This mass exchange appears as a source of mass in the continuous phase continuity equation and as a source of a chemical species defined by you. The mass sources are included in any subsequent calculations of the continuous phase flow field and are reported by ANSYS FLUENT as described in this section in the separate User's Guide.
