A Favre-Averaging Shallow Water Framework for Aerated Flows with Friction Factor Decomposition
Matthias Kramer
Accurate prediction of flow resistance in high-Froude-number aerated flows remains challenging due to air entrainment, which causes strong spatial variability in mixture density. H…
Clustering and surface distributions of buoyant particles in open-channel flows
Ana Todorova, Robert K. Niven, Matthias Kramer
This study investigates the clustering behaviour and surface distributions of buoyant particles at the air-water interface in open-channel turbulent flow, focusing on the interplay…
On the estimation of specific interfacial areas in aerated flows
Matthias Kramer
This work provides a short clarification on the definition of specific interfacial areas in aerated flows, thereby distinguishing between the specific interfacial area related to t…
Surface detachment and bed entrainment of fluvial plastics
Matthias Kramer
Over the last decade, fluvial plastics have been identified as major threat to aquatic environments and human health. In order to develop adequate mitigation strategies for plastic…
Developing the next generation of dual-tip phase-detection probes for air-water flow experiments
Matthias Kramer
Self-aeration is a fascinating phenomenon that commonly occurs in high Froude-number flows in natural or human made environments. The most common air-water flow measurement instrum…
