Large-Eddy Simulation of Contrails [PDF]

Journal of the Atmospheric Sciences, 1998
Numerical simulations of contrails have been performed to investigate the role of various external parameters and physical processes in the life cycle of contrails. The general idea underlying the model is that of a largeeddy model. The model explicitly represents the large-scale three-dimensional motions (10-m grid resolution), while small-scale ...

Large-Eddy Simulation of combustion instabilities in a variable-length combustor. [PDF]

, 2013
This article presents a simulation of a model rocket combustor with continuously variable acoustic properties thanks to a variable-length injector tube. Fully compressible Large-Eddy Simulations are conducted using the AVBP code.

When Does Eddy Viscosity Damp Subfilter Scales Sufficiently? [PDF]

, 2011
Large eddy simulation (LES) seeks to predict the dynamics of spatially filtered turbulent flows. The very essence is that the LES-solution contains only scales of size ≥Δ, where Δ denotes some user-chosen length scale. This property enables us to perform

Statistical ensemble of large-eddy simulations [PDF]

Journal of Fluid Mechanics, 2002
A statistical ensemble of large-eddy simulations (LES) is run simultaneously for the same flow. The information provided by the different large-scale velocity fields is used in an ensemble-averaged version of the dynamic model. This produces local model parameters that only depend on the statistical properties of the flow.

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.

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 ...
