Phase-field simulation of interfacial stability in structured gas-liquid contactors: design rules for gas diffusion electrodes
Alexander J. Wagner, Hari Murali Krishna Varma Gottumukkala, Henning Bonart
Many process engineering applications hold a gas-liquid interface stationary inside a structured solid by a controlled pressure difference. Gas diffusion electrodes (GDEs) are one…
Reversibility and Multiplicity in Liquid-Vapor Phase Change
Luiz Eduardo Czelusniak, Alexander J. Wagner, Luben Cabezas Gómez
Using diffuse-interface theory, we uncover unexpected phase-change phenomena that are absent from widely used models of evaporation and condensation. In the inviscid limit, the sam…
Mirror states enable lower viscosity lattice gases
Noah Seekins, Alexander J. Wagner
We developed a method for significantly lowering the viscosity achievable for a hydrodynamic lattice gas method. The key advance is the derivation of a mirror state that allows for…
Analytical solution for dynamic evaporation of liquid in isothermal condition
Luiz Eduardo Czelusniak, Tim Niklas Bingert, Stephan Simonis +2
An analytical solution based on a diffuse interface model is presented for an isothermal evaporation problem under sub-saturation pressure. The macroscopic equations are derived fr…
A Method for Analytical Solutions in the Lattice Boltzmann Method
Jordan Larson, Alexander J. Wagner
Analytical solutions to the lattice Boltzmann Equation make it possible to study the method itself, explore the properties of its collision operator, and identify implementations o…
Convection can enhance the capacitive charging of porous electrodes
Aaron D. Ratschow, Alexander J. Wagner, Mathijs Janssen +1
Charge transport in porous electrodes is foundational for modern energy storage technologies like supercapacitors, fuel cells, and batteries. Supercapacitors in particular rely sol…
