Macroscopic continuum simulations can be based on an unstructured moving spatial grid made up of “smooth particles”. The smooth particles’ equations of motion include interpolated values of the macroscopic stress gradient at each particle’s position. Microscopic solid-state simulations...

A pressure (density) and a corner no-slip boundary condition formulation are introduced for the two-dimensional lattice Boltzmann method and numerically tested for the Hagen–Poiseuille flow case in this work. Both formulations are derived independently of the equilibrium distribution function...

Serpentine flow-fields are widely used for polymer electrolyte membrane (PEM) fuel cells due to effective water removal. In this study, the effects of serpentine flow-field designs on the performance of a commercial-scale PEM fuel cell stack for micro-CHP (Combined Heat & Power) systems, which...

Many computational fluid dynamics polymer-electrolyte-membrane fuel cell models have been presented over the last few decades. A detailed literature overview of models, ranging from one-dimensional, single-component to complete three-dimensional, large-scale setups, is presented with an emphasis...
