Hi,

Saw in some tutorials that UDF can be used to specify the interphase heat and mass transfer for boiling, e.g. using the RPI model for subcooled nucleate boiling. Does anyone has this udf handy? I am not too familiar with UDF and it might be easier for me to start from there.

Thanks!

hello dear jake;
do you find or write udf for nucleate boiling?i am similar you!!!

Hi
There is no need to UDF
The new versions of Ansys fluent and Ansys CFX can simulate this
but fluent can't simulate condensation during wall boiling, so you should use udf for condensation mass transfer between phases.
