Implementing a UDS.

I am trying to implement the following UDS in Fluent multiphase mixture model (in Untitled, N is the scalar variable for the solid phase).

But in the Fluent manual the following UDS equation is given for a phase.(Untitled1.jpg)

I got that I have to take diffusivity as zero and since I am taking density constant for solid phase it gets cancelled ,source term is zero,
but i am concerned about the volume fraction term.

How to remove the volume fraction term so that the UDS equation in the manual equals my UDS equation?
