Bottom Current Modification of Turbidite Lobe Complexes

Frontiers in Earth Science, 2022
Submarine lobes form at the distal end of sediment gravity flow systems and are globally important sinks for sediment, anthropogenic pollutants and organic carbon, as well as forming hydrocarbon and CO2 reservoirs.

Numerical Modeling of turbidity currents with Ansys CFX and Telemac 3D

E3S Web of Conferences, 2018
Turbidity currents may be a relevant lever to manage the accumulation of fine sediments in reservoirs. In this paper, we propose to show how two different numerical codes simulate the propagation of turbidity currents.

Prediction criterion of turbidity current formation in reservoir

Shui kexue jinzhan, 2012
Sediment deposition is a big problem that affects the lifespan of reservoirs in heavily sediment-laden rivers.Furthermore,venting turbidity currents is an important measure to reduce the sedimentation in reservoirs,especially at the initial operation ...

CFD-DEM modeling of turbidity current propagation in channels with two different topographic configurations

Frontiers in Marine Science, 2023
Submarine turbidity currents are a special type of sediment gravity flow responsible for turbidite deposits, attracting great interests from scientists and engineers in marine and petroleum geology. This paper presents a fully coupled computational fluid

Modeling of Breaching-Generated Turbidity Currents Using Large Eddy Simulation

Journal of Marine Science and Engineering, 2020
Breaching flow slides result in a turbidity current running over and directly interacting with the eroding, submarine slope surface, thereby promoting further sediment erosion. The investigation and understanding of this current are crucial, as it is the

Self-stratifying turbidity currents

, 2022
Turbidity currents, seafloor flows driven by the excess density of suspended particles, are key conveyors of sediment, nutrient, and pollutant from the continental margins to deep ocean, and pose critical submarine geohazard risks. Due to their vast scale and extreme aspect ratio, extant models are constrained to highly simplified depth-averaged theory

Pulse propagation in turbidity currents [PDF]

Sedimentology, 2017
AbstractSubmarine turbidity currents are a key mechanism in the transportation of clastic sediments to deep seas. Such currents may initiate with a complex longitudinal flow structure comprising flow pulses (for example, by being sourced from retrogressive sea floor slope failures) or acquire such structure during run‐out (for example, following flow ...

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Turbulent diffusion modelling of sediment in turbidity currents: An experimental validation of the Rouse approach

The Depositional Record, 2020
The margins of submarine channels are characterized by deposits that fine away from the channel thalweg. This grain‐size trend is thought to reflect upward fining trends in the currents that formed the channels.
