How to choose the YPLUS value in two-phase flows?
 
For two-phase Euler-Euler multiphase model + turbulence model, how to select the reported "yplus" values for meeting the requirement of law-of-the-wall?

I mean, there are two "yplus" values from different phases (say, YPLUS for air & solid). Then, which one should be chosen for the grid adjustment?

Especially, for the MIXTURE and DISPERSED models (k-epsilon multiphase turbulence model), how to make decision for the YPLUS value?

Please give your idea.
