Linking turbulent waves and bubble diffusion in self-aerated open-channel flows: Two-state air concentration
Matthias Kramer, Daniel Valero
High Froude-number flows become self-aerated when the destabilizing effect of turbulence overcomes gravity and surface tension forces. Traditionally, the resulting air concentratio…
Urban Flood Drifters (UFDs): identification, classification and characterisation
Arnau Bayón, Daniel Valero, Mário J. Franca
Extreme floods threaten lives, assets and ecosystems, with the largest impacts occurring in urbanised areas. However, flood mitigation schemes generally neglect the fact that urban…
Microplastic and natural sediment in bed load saltation: material does not dictate the fate
James Lofty, Daniel Valero, Catherine A. M. E. Wilson +2
Microplastic (MP) pollution is a well document threat to our aquatic and terrestrial ecosystems, however, the mechanisms by which MPs are transported in river flows are still unkno…
Unsteady shallow meandering flows in rectangular reservoirs: A modal analysis of URANS modelling
Daniel Valero, Daniel B. Bung, Sebastien Erpicum +2
Shallow flows are common in natural and human-made environments. Even for simple rectangular shallow reservoirs, recent laboratory experiments show that the developing flow fields…
Best practices for velocity estimations in highly aerated flows with dual-tip phase-detection probes
Matthias Kramer, Benjamin Hohermuth, Daniel Valero +1
Dual-tip phase-detection probes can be used to measure flow properties in gas-liquid flows. Traditionally, time-averaged interfacial velocities have been obtained through cross-cor…
Turbulence and self-similarity in highly-aerated shear flows: the stable hydraulic jump
Matthias Kramer, Daniel Valero
Hydraulic jumps are oftentimes encountered in natural and human-made environments. The transition from supercritical to subcritical flow involves large energy dissipation rates and…
Robust estimators for turbulence properties assessment
Daniel Valero, Hubert Chanson, Daniel B. Bung
Robust estimators and different filtering techniques are proposed and their impact on the determination of a wide range of turbulence quantities is analysed. High-frequency water l…
