Fig. 7
Effective chemical potential depending on the size of the RVE
and the mobility parameter of the matrix. The evolution of the
macroscopic chemical potential \({\overline{\mu }}\) for different realizations of RVEs is depicted as a
function of the divergence of the macroscopic solvent-volume flux
for selected mobility parameters of the matrix given
by a
\(M_{mat}=0.1~\text {mm}^4/(\text {Ns})\) and b
\(M_{mat}=5.0~\text {mm}^4/(\text {Ns})\). Like in the previous study (Fig. 6) we observe that the effective
chemical potential \({\overline{\mu }}\) depends strongly on the size of the RVE. The
observed discrepancies decrease with increasing mobility parameter of
the matrix
