Abstract Strength, ductility, and failure properties of metals are tailored by plastic deformation routes. Predicting these properties requires modeling of the structural dynamics and stress evolution taking place on several length scales. Progress h

The use of a phase-retrieval technique for propagation-based phase-contrast neutron imaging with a polychromatic beam is demonstrated. This enables imaging of samples with low absorption contrast and/or improving the signal-to-noise ratio to facilita

Crystallisation fouling is a challenge in numerous applications. To mitigate fouling we need to determine the basic mechanisms involved in the process. While ex situ techniques have been widely used in previous studies, they cannot capture complex dy

Simulating Anomalous Dispersion in Porous Media Using the Unstructured Lattice Boltzmann Method

Autor: Marek Krzysztof Misztal, Anier eHernandez-Garcia, Rastin eMatin, Dirk eMüter, Diwaker eJha, Henning Osholm Sørensen, Joachim eMathiesen

Publikováno v: Frontiers in Physics, Vol 3 (2015)

Flow in porous media is a significant challenge to many computational fluid dynamics methods because of the complex boundaries separating pore fluid and host medium. However, the rapid development of the lattice Boltzmann methods and experimental
