Detailed numerical simulations were conducted of gravity currents released from a lock and propagating at the bottom of a linearly stratified ambient. The objective is to test the predictions of theâ€¦ (More)

The intrusion of a fixed volume of fluid which is released from rest and then propagates horizontally at the neutral buoyancy level in a vertically-stratified ambient fluid is investigated. Theâ€¦ (More)

The exchange of energy for an inviscid gravity current which is released from a lock and then propagates over a horizontal boundary is considered. Attention is focused on effects due toâ€¦ (More)

We consider the propagation of a high-Reynoldsnumber gravity current at the bottom of a horizontal channel along the horizontal coordinatex. The bottom and top of the channel are at z = 0, H, and theâ€¦ (More)

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. A numerical investigation of high-Reynolds-numberâ€¦ (More)

We explore the phenomenon of segregation and pattern formation in the complex system of a rotating horizontal cylinder completely filled with a dilute suspension of non-Brownian particles. A generalâ€¦ (More)

Gravitationally driven motion arising from a sustained constant source of dense fluid in a horizontal channel is investigated theoretically using shallow-layer models and direct numerical simulationsâ€¦ (More)

An extensive experimental investigation into the segregation phenomenon of suspended particles in a rotating fluid-filled horizontal cylinder is presented as well as a theoretical approach to theâ€¦ (More)

Non-Brownian particles suspended at low volume concentration in a rotating horizontal cylinder filled with a low-viscosity fluid are observed to segregate into well-defined periodic axial bands. Weâ€¦ (More)
