Default Mixture-model typo in FLUENT6.2 documentation?

Hello. Regarding FLUENT's mixture model: Equation 24.3-11 defines the relationship between drift-velocity, MASS FRACTION and relative velocity.

The document in FLUENT's Bibliography [216](Manninen et al.) defines drift velocity as "the velocity of the dispersed phase relative to that of the volume centre of a mixture" (p.20). Manninen also defines diffusion velocity as "the velocity of phase k relative to the centre of the mixture mass" (p.18). In Manninen (p.20) they define the relationship between drift-velocity, VOLUME FRACTION and relative velocity.

According to Manninen it appears as if FLUENT is using a diffusion velocity equation and presenting it as the definition for drift-velocity.
