You can report on the mass and energy fluxes for the Eulerian Wall Film model using the Flux Reports dialog box (see Generating a Flux Report), for domain boundaries such as inlets, outlets, and so on, as well as wall boundaries.

 Results → Reports → Fluxes   Edit...

The Film Mass Flow Rate and Film Heat Transfer Rate are available as options in the Flux Reports dialog box when the Eulerian Wall Film model is enabled.

Note:  The energy flux report only accounts for the heat transfer rate through the external boundary. It does not consider heat transfer at gas-liquid interfaces or heat transfer due to phase change or film-DPM interaction.

You can also report on the mass flow rate and heat transfer rate using the User Interface (TUI) as follows:

  • For mass flow rate, enter the text command report/fluxes/film-mass-flow.

  • For heat transfer  rate, enter the text command report/fluxes/film-heat-transfer.

You will be prompted for the boundary face zone IDs for which the report will be generated, and whether or not you want to save the reported values to a file. Ansys Fluent will either print the report in the console or write it to the file you have specified.
