Spatial evolution of turbulence characteristics in weak hydraulic jumps
(TAYLOR & FRANCIS LTD, 2011)
This experimental investigation focuses on the turbulence features of weak hydraulic jumps in rectangular channels for two different approach flow lengths. The turbulent kinetic energy equation includes the turbulence ...
Simulations of turbulent channels with prescribed velocity profiles
(Cambridge University Press, 2013-05)
Direct numerical simulations of turbulent channels with artificially prescribed velocity profiles are discussed, using both natural and purposely incorrect profiles. It is found that turbulence develops correctly when ...
Development of a low-Reynolds-number k-ω model for FENE-P fluids
(2013-01-01)
A low-Reynolds-number k-ω model for Newtonian fluids has been developed to predict drag reduction of viscoelastic fluids described by the FENE-P model. The model is an extension to viscoelastic fluids of the model for ...

Lagrangian and Eulerian perspectives of turbulent transport mechanisms in a lateral cavity
(2024)
The dynamics of turbulent flows past lateral cavities is relevant for multiple environmental applications. In rivers and coastal environments, these lateral recirculating regions constitute surface storage zones, where ...
Flow-sediment turbulent ejections: interaction between surface and subsurface flow in gravel-bed contaminated by fine sediment
(MDPI, 2020)
Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, ...
Numerical simulation of a radial diffuser turbulent airflow
(Elsevier B.V., 2007-06-15)
In the present work are presented results from numerical simulations performed with the ANSYS-CFX (R) code. We have studied a radial diffuser flow case, which is the main academic problem used to study the flow behavior ...

Coherent turbulent structures at the mixing-interface of a square open-channel lateral cavity
(2016)
The self-sustained turbulent shear or mixing layer that develops at the interface between a channel and a lateral cavity is the leading mechanism that drives the transfer of momentum and mass in these open-channel flows. ...
