Multiphase flow mixture polymere with dichlormethan and water

i want to simulate the mixture from water and polymer dissolved in dichllormethan in a pipe. In the reality Dichlomethan evaporates and the whole viscosity increases. i want to know how i can set it up in Ansys  

Thank you

Are you interested in the period when the solvent is evaporating, or after it's already gone?  The former is not simple and will need a mulitphase model with species & phase change. The latter will use a single species and you just need to alter the viscosity (possibly using a nonNewtonian model).

I thank you first for your answers. I make a mixture between a compound A + B -> C
I know the viscosity and density of A, B, C.
Then I have to mix C to D: C + D -> E. I also have the density and the viscosity of D and E.
At each step the viscosity increases.
What is of interest is to materialize this in a static mixer.
I already drew the mixer but I do not get the viscosity of C and E
