Not that I know of. I assume that as far as the multiphase flow is
concerned, both aqueous and polymeric behave the same, but within the
water phase these two components may have different concentrations that
affect the properties of the aqueous phase?
The way I would probably describe this is via another field that is
interpreted as a volume or mass fraction *within the water phase* of the
polymeric phase.
It would probably also be useful for you to take a look at the
literature on the "black-oil equations". That's a 3-phase flow problem
(oil, water, gas) but where some of the gas can be dissolved in the
other phases. You might find interesting techniques for this problem
that are also applicable to your problem.
