Intermittent turbulence in inclined gravity currents
Lianzheng Cui, Graham O. Hughes, Maarten van Reeuwijk
Inclined gravity currents on shallow slopes can exhibit pronounced turbulence intermittency. Using direct numerical simulations, we investigate this behaviour for a temporal gravit…
Inpainting U-Net for seamless pedestrian-level wind prediction across urban morphologies
Jingzi Huang, Claire E. Heaney, Tao Li +3
Pedestrian-level wind prediction is essential for urban design and wind-comfort assessment, but high-fidelity simulations such as LES remain computationally expensive for rapid eva…
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…
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…
