two models are distinct.

The well-mixed model implies something concrete, i.e. c(x,y,z,t) = c(t). Non-uniform mixing and the concept of mixing factor mean that the equality does not hold, but the concept does not predict how, where, or in what way the concentration varies. The present authors recommend that the use of mixing factors be abandoned.Web
