S Chawdhary, A Khosronejad, G Christodoulou… - International Journal of …, 2018 - Elsevier
We carry out high-resolution large-eddy simulation (LES) of stratified flows developing as
dense underflows over two different bed slopes of 5° and 15° in an laboratory-scale tank …

[HTML][HTML] Mixing in density-and viscosity-stratified flows

PA Allen, RM Dorrell, OG Harlen, RE Thomas… - Physics of …, 2022 - pubs.aip.org
The lock-exchange problem is used extensively to study the flow dynamics of density-driven
flows, such as gravity currents, and as a canonical problem to mixing in stratified flows …

Front dynamics of elliptical gravity currents on a uniform slope

SJ Zhu, N Zgheib, S Balachandar, A Ooi - Physical Review Fluids, 2017 - APS
In the present investigation, we report data from direct numerical simulations of elliptical,
finite release, Boussinesq gravity currents propagating down a uniform slope. The study …

A two-dimensional layer-averaged numerical model for turbidity currents

S Yang, Y An, Q Liu - Geological Society, London, Special …, 2019 - lyellcollection.org
Turbidity currents occur widely in submarine environments, but field-scale numerical
simulations of the flow features have not been applied extensively. Here, we present a two …

Numerical modeling of submarine turbidity currents over erodible beds using unstructured grids

X Liu, JÁI Sedano, A Mohammadian - Ocean Modelling, 2017 - Elsevier
Second-order central-upwind schemes proposed by Bryson et al.(2011) for the Saint–
Venant system have two very attractive properties: well-balanced and positivity preserving …

Stability of complex gravity currents in coastal environment

A Maskoni - 2023 - theses.hal.science
The coast is the contact zone between the continent and the sea. It is therefore likely to
collect polluted liquids coming from both the sea and the continent. This thesis considers the …

[PDF][PDF] CHARACTERISTICS OF DENSITY CURRENT DYNAMICS OVER ROUGH CHANNEL BEDS

R NASROLLAHPOUR - 2018 - eprints.utm.my
Density currents occur in a variety of natural and man-made scenarios, and this emphasises
the importance of studying them. The density-driven currents are the main agent for …
