where σT is the turbulent particle Schmidt number (dimensionless). The particle Schmidt number is usually suggested as a value ranging from 0.35 to 0.7. In the physics interface the default value is 0.35. The so-called drift velocity is included in
Equation 6-47 as a diffusion term
The inclusion of the drift velocity in Equation 6-47 modifies the flux of the dispersed phase. The effective dispersed phase flux
jd,eff and velocity
ud,eff are given by
jd,eff and
ud,eff are available in the physics interface as
mm.jdEff and
mm.udEff.
