A Neutrally Stratified Boundary-Layer: A Comparison of Four Large-Eddy-Simulation Computer Codes

, 1994
A neutrally stratified Ekman layer limited in depth by a stress-free rigid lid has been simulated using four different large-eddy simulation computer codes.

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

Large-eddy simulation of multi-component compressible turbulent flows using high resolution methods [PDF]

, 2008
The ability of a finite volume Godunov and a semi-Lagrangian large-eddy simulation (LES) method to predict shock induced turbulent mixing has been examined through simulations of the half-height experiment [Holder and Barton.

Large-eddy simulation of low-frequency unsteadiness in a turbulent shock-induced separation bubble

, 2009
The need for better understanding of the low-frequency unsteadiness observed in shock wave/turbulent boundary layer interactions has been driving research in this area for several decades.

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

High precision implicit large eddy simulation based on dissipation adaptive adjustment

Kongqi donglixue xuebao
The implicit large eddy simulation has received widespread attention due to the fact that it does not require additional design to construct the explicit subgrid scale model, but how to regulate its own numerical dissipation such that the numerical ...

Large-eddy simulation of maritime deep tropical convection

Journal of Advances in Modeling Earth Systems, 2009
This study represents an attempt to apply Large-Eddy Simulation (LES) resolution to simulate deep tropical convection in near equilibrium for 24 hours over an area of about 205 x 205 km2, which is comparable to that of a typical horizontal grid cell in a

Large-Eddy Simulation Analyses of Heated Urban Canyon Facades

Energies, 2021
Thermal convective flows are common phenomena in real urban canyons and strongly affect the mechanisms of pollutant removal from the canyon. The present contribution aims at investigating the complex interaction between inertial and thermal forces within

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
