Implementation of Non dimensionalization

Hello,
I am facing problems with the implementation of non-dimensional coefficents in COMSOL. Attached is the final equation of N-S we arrived at post non dimensionalisation. As you can observe that the term associated with alpha and Re is only present for local acceleration. Whereas in COMSOL's equations corresponding coefficients of acceleration terms are not separated (Incompressible Flow). Is there a way to implement it in the Laminar Flow module or programming the N-S using coefficient of PDE is the only way.
