Hi,
I am trying to write UDF for simulating evaporation of a liquid into its vapor. This UDF is to be used with VOF method. 1. I want to add source terms in continuity or volume fraction equations of each phase to account for evaporation and condensation of liquid or vapor. 2. I want to add source term in energy equation to account for the heat of evaporation and condensation. In this regard, which macro out of the following is effective? A. DEFINE_ADJUST + DEFINE_MASS_TRANSFER B. DEFINE_SOURCE C. DEFINE_ON_DEMAND Thanks in advance! vidyadhar Last edited by vidyadhar; November 2, 2018 at 08:25. Reason: to add more tags |
