Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

open access: yesEnergies, 2014
In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow.

WRF-LES Simulation of the Boundary Layer Turbulent Processes during the BLLAST Campaign

open access: yesAtmosphere, 2020
A real case long-term nested large eddy simulation (LES) of 25-day duration is performed using the WRF-LES modelling system, with a maximum horizontal grid resolution of 111 m, in order to explore the ability of the model to reproduce the turbulence ...

Regularization modeling for large-eddy simulation of diffusion flames [PDF]

open access: yes, 2006
We analyze the evolution of a diffusion flame in a turbulent mixing layer using large-eddy simulation. The large-eddy simulation includes Leray regularization of the convective transport and approximate inverse filtering to represent the chemical source ...

Numerical analysis of lifted hydrogen flame

open access: yesMATEC Web of Conferences, 2018
A numerical analysis of a turbulent lifted H2/N2 flame is presented. As combustion mechanisms, a large spectrum is considered including single-step and two-step, as well as detailed mechanisms.

What Controls the Water Vapor Isotopic Composition Near the Surface of Tropical Oceans? Results From an Analytical Model Constrained by Large‐Eddy Simulations

open access: yesJournal of Advances in Modeling Earth Systems, 2020
The goal of this study is to understand the mechanisms controlling the isotopic composition of the water vapor near the surface of tropical oceans, at the scale of about a hundred kilometers and a month. In the tropics, it has long been observed that the

Large-eddy simulation for flow and dispersion in urban streets

open access: yes, 2009
Large-eddy simulations (LES) with our recently developed inflow approach (Xie &Castro, 2008a) have been used for flow and dispersion within a genuine city area -the DAPPLE site, located at the intersection of Marylebone Rd and Gloucester Plin Central

Large eddy simulation of auto-igniting methanol/n-dodecane blend spray flames

open access: yesFuel Processing Technology
The study investigates the auto-ignition characteristics of methanol/n-dodecane fuel blends at varying blend ratios and ambient temperatures using large eddy simulation (LES) in OpenFOAM with the Engine Combustion Network (ECN) Spray-D injector.

Toward Low‐Level Turbulence Forecasting at Eddy‐Resolving Scales

open access: yesGeophysical Research Letters, 2018
Microscale turbulence in the atmospheric boundary layer (ABL) is characterized by significant spatiotemporal variability. Consequently, a change in the turbulence forecasting paradigm needs to occur, moving beyond average turbulence estimates at ...

Direct numerical simulation and large-eddy simulation of stationary buoyancy-driven turbulence [PDF]

open access: yes, 2010
We report direct numerical simulation (DNS) and large-eddy simulation (LES) of statistically stationary buoyancy-driven turbulent mixing of an active scalar. We use an adaptation of the fringe-region technique, which continually supplies the flow with

A coupled approximate deconvolution and dynamic mixed scale model for large-eddy simulation

open access: yes, 2007
Large-eddy simulations of incompressible Newtonian fluid flows with approximate deconvolution models based on the van Cittert method are reported. The Legendre spectral element method is used for the spatial discretization to solve the filtered Navier ...
