Pore-network models and effective medium theory: A convergence analysis
Jack Edwards, Peter Berg
The convergence between effective medium theory and pore-network modelling is examined. Electrical conductance on two and three-dimensional cubic resistor networks is used as an ex…
Modeling, shape analysis and computation of the equilibrium pore shape near a PEM-PEM intersection
Peter Berg, Sven-Joachim Kimmerle, Arian Novruzi
In this paper we study the equilibrium shape of an interface that represents the lateral boundary of a pore channel embedded in an elastomer. The model consists of a system of PDEs…
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…
Mass Transport Phenomena in a MCFC Cathode
Peter Berg, Justin Findlay
A molten carbonate fuel cell (MCFC) is an electro-chemical energy conversion technology that runs on natural gas and employs a molten salt electrolyte. In order to keep the electro…
Flow Patterns of Cellular Automata and Optimal-velocity Traffic Models at Highway Bottlenecks
Peter Berg, Justin Findlay
A bottleneck simulation of road traffic on a loop, using the deterministic cellular automata (CA) Nagel-Schreckenberg model with zero dawdling probability, reveals three types of s…
