Interface dynamics in a degenerate Cahn-Hilliard model for viscoelastic phase separation
Katharina Hopf, John King, Andreas Münch +1
The formal sharp-interface asymptotics in a degenerate Cahn-Hilliard model for viscoelastic phase separation with cross-diffusive coupling to a bulk stress variable are shown to le…

An asymptotic model of Poisson--Nernst--Planck--Stokes systems in narrow channels
Christine Keller, Andreas Münch, Barbara Wagner
Ion transport through narrow channels is described by the coupled Poisson--Nernst--Planck--Stokes equations (PNPS) on a continuum scale. However, direct numerical simulations in tw…

The diffusive dynamics and electrochemical regulation of weak polyelectrolytes across liquid interfaces
Giulia Laura Celora, Ralf Blossey, Andreas Munch +1
We propose a framework to study the spatio-temporal evolution of liquid-liquid phase separation of weak polyelectrolytes in ionic solutions. Unlike strong polyelectrolytes, which c…
