Difference between Macros for evaporation Mass Trnasfer

mohibanwar · February 26, 2019, 21:35

Good Morning Seniors,

Recently i am Modelling Evaporation with UDF using VOF. I found the following two Macros for the Calculating Mass transfer at Interface:

1. Add Mass and Energy Sources using 'DEFINE SOURCE' Macro and then hook up the sources udf from the source menu. In this case i am confused what i have to input the 'Phase Interaction Menu of VOF'

2. Can Use the " DEFINE_MASS_TRANSFER" and hook the udf in the Phase interaction menu of VOF. But in this case i am so confused that whether both the Energy and Mass Sources will be added in response to this macro or i have to add them seperatly.

Thank you so much for your suggestion to remove confusion in the mind. By the way i have seen the UDF manual before writing this confusion here.

Kind Regards,
Khan
