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

Bottom mixed layer oxygen dynamics in the Celtic Sea [PDF]

, 2020
The seasonally stratified continental shelf seas are highly productive, economically important environments which are under considerable pressure from human activity.

A 3D Numerical Model for Turbidity Currents

WSEAS TRANSACTIONS ON FLUID MECHANICS, 2020
A numerical model that solves two-phase flow motion equations to reproduce turbidity currents that occur in reservoirs, is proposed. Three formalizations of the two-phase flow motion equations are presented: the first one can be adopted for high concentration values; the second one is valid under the hypothesis of diluted concentrations; the third one ...

Turbidity Current Bedforms [PDF]

, 2016
Turbidity currents in the submarine seascape are what river flows are in terrestrial landscapes. While rivers transport sediment from the mountains through valleys towards the sea, turbidity currents transport sediment from the shallow marine realms through canyons towards the deeper abyssal plains.

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.

Sedimentary processes and architecture of Upper Cretaceous deep-sea channel deposits : a case from the Skole Nappe, Polish Outer Carpathians [PDF]

, 2018
Deep-sea channels are one of the architectonic elements, forming the main conduits for sand and gravel material in the turbidite depositional systems.

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
