multiphase flow
 

Hi, I am trying to model multiphase flow, with evaporation. I am using the VOF model. In order to simulate the mass transfer due to the evaporation, I use the DEFINE_EXCHANGE_PROPERTY. I have an equation that gives me the mass flux at the interface between the liquid and the gas. Is there anybody that could tell me with which macro I could get the face area of the interface in a cell (so I could multiply it by the mass flux)?

Thank in advance

Gilad.

try NV_MAG(A)

thank you, NV_MAG(A) can compute the area of specific area, but how could I get the vector of that interface area (between the two phases)? the face cen cross the cell (not in his boundry?

thank in advance
