Published in 2020 at "Scientific Reports"

DOI: 10.1038/s41598-020-62827-w

Abstract: Particle shape analysis is conducted, to compare two types of railway ballast: Calcite and Kieselkalk. Focus lies on the characterisation of particle angularity using 3D scanner data. In the literature, angularity is often characterised using… read more here.

Published in 2019 at "Energies"

DOI: 10.3390/en12234575

Abstract: The Volvo Cars aerodynamic wind tunnel has had a vortical flow angularity pattern in the test section since its original commissioning in 1986. The vortical flow nature persisted after an upgrade in 2006, when the… read more here.

Published in 2020 at "Materials"

DOI: 10.3390/ma13020492

Abstract: Under the repeated loading, the continuous impact and friction of tires on aggregates resulted in some changes in their morphology, which may cause rutting, decrease in skid resistance, and fatigue damage of the road. In… read more here.
