Large Eddy Simulation of Turbulent Channel Flows by the Rational LES Model

, 2002
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade') approximation of the Fourier transform of the Gaussian filter and is proposed as an ...

Large Eddy Simulation of Vented Deflagration [PDF]

, 2013
In order to understand gas explosion phenomena in industrial buildings, a reduced-scale vented combustion 6 chamber is investigated numerically. In this configuration, a flame is ignited in an initially quiescent flammable mixture and 7 propagates past

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Rain Evaporation, Snow Melt, and Entrainment at the Heart of Water Vapor Isotopic Variations in the Tropical Troposphere, According to Large‐Eddy Simulations and a Two‐Column Model

Journal of Advances in Modeling Earth Systems, 2021
We aim at developing a simple model as an interpretative framework for the water vapor isotopic variations in the tropical troposphere over the ocean. We use large‐eddy simulations of disorganized convection in radiative‐convective equilibrium to justify

A physical-space version of the stretched-vortex subgrid-stress model for large-eddy simulation [PDF]

, 2000
A physical-space version of the stretched-vortex subgrid-stress model is presented and applied to large-eddy simulations of incompressible flows. This version estimates the subgrid-kinetic energy required for evaluation of the subgrid-stress tensor using

Inverse modeling for large-eddy simulation [PDF]

Physics of Fluids, 1997
Approximate higher order polynomial inversion of the top-hat filter is developed with which the turbulent stress tensor in large-eddy simulation can be consistently represented using the filtered field. Generalized (mixed) similarity models are proposed which improved the agreement with the kinetic energy transfer to small scales.
