16.7 Modeling Mass Transfer in Multiphase Flows

This section describes the modeling of mass transfer in the framework of ANSYS FLUENT's general multiphase models (i.e., Eulerian multiphase, mixture multiphase, VOF multiphase). There are numerous kinds of mass transfer processes that can be modeled in ANSYS FLUENT. You can use models available in ANSYS FLUENT (e.g. ANSYS FLUENT's cavitation model), or define your own mass transfer model via user-defined functions. See Section  16.7.3 and the separate UDF Manual for more information about the modeling of mass transfer via user-defined functions.
