Revisiting the phenomenon of bouncing of inertial particles crossing density stratified interfaces
Chen Mortenfeld, Maarten van Reeuwijk, Aviv Littman +1
Inertial spheres settling through sharp density interfaces can arrest, reverse direction, and resume descent, a phenomenon known as bouncing. Using synchronized particle image velo…
Particle settling in turbidity currents: inertia-independent biased sampling
Lianzheng Cui, Eric Climent, Graham O. Hughes +1
We investigate the mechanisms governing particle settling in turbidity currents using Eulerian-Lagrangian direct numerical simulations. The Eulerian carrier flow is driven either b…
Multi-scale flow analysis for scale-aware urban-canopy models
Jingzi Huang, Maarten van Reeuwijk
As Numerical Weather Prediction (NWP) models approach hectometric resolution, they increasingly enter a regime where urban heterogeneity is only partially resolved and the assumpti…
Structure and scaling of inclined gravity currents
Lianzheng Cui, Graham O. Hughes, Maarten van Reeuwijk
We explore the fundamental flow structure of inclined gravity currents with direct numerical simulations. A velocity maximum naturally divides the current into inner and outer shea…
