Derivation of effective macroscopic Stokes-Cahn-Hilliard equations for periodic immiscible flows in porous media
Markus Schmuck, Marc Pradas, Gregorios A. Pavliotis +1
Using thermodynamic and variational principles we examine a basic phase field model for a mixture of two incompressible fluids in strongly perforated domains. With the help of the…
New porous medium Poisson-Nernst-Planck equations for strongly oscillating electric potentials
Markus Schmuck
We consider the Poisson-Nernst-Planck system which is well-accepted for describing dilute electrolytes as well as transport of charged species in homogeneous environments. Here, we…
Upscaled phase-field models for interfacial dynamics in strongly heterogeneous domains
Markus Schmuck, Marc Pradas, Greg A. Pavliotis +1
We derive a new effective macroscopic Cahn-Hilliard equation whose homogeneous free energy is represented by 4-th order polynomials, which form the frequently applied double-well p…
Homogenization of a catalyst layer model for periodically distributed pore geometries in PEM fuel cells
Markus Schmuck, Peter Berg
We formally derive an effective catalyst layer model comprising the reduction of oxygen for periodically distributed pore geometries. By assumption, the pores are completely filled…
Homogenization of the Poisson-Nernst-Planck Equations for Ion Transport in Charged Porous Media
Markus Schmuck, Martin Z. Bazant
Effective Poisson-Nernst-Planck (PNP) equations are derived for macroscopic ion transport in charged porous media under periodic fluid flow by an asymptotic multi-scale expansion w…
A New Mode Reduction Strategy for the Generalized Kuramoto-Sivashinsky Equation
M. Schmuck, M. Pradas, G. A. Pavliotis +1
Consider the generalized Kuramoto-Sivashinsky (gKS) equation. It is a model prototype for a wide variety of physical systems, from flame-front propagation, and more general front p…
