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…

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…
