## 5.4. Multicomponent Multiphase Flow

In multiphase multicomponent flows, transport equations for the mass fractions of components are assumed to take a similar form those used for single-phase multicomponent flow:

| (5–31)

You should note that the molecular diffusion coefficients are given by , where is the Kinematic Diffusivity.

Source terms in multicomponent multiphase flow behave the same as multicomponent mass sources, but on a per fluid basis. For details, see Sources.
