Mass transfer rate in 2D simulation
 

Hi there,

I am trying to model the evaporation of a swimming pool using the VOF and Lee model. A UDF has been hooked to restrict the evaporation only happens on the interface. I notice that in the post-processer, the unit of Phase Interaction - Mass transfer rate is in kg/m^3 s. However, in order to compare with others' experimental results, the unit should be kg/m^2 s. Any idea of how to convert the unit?

Thanks

Since its 2D simulation, m^3 can be interpreted as unit depth.
