Simulations of the flow around a circular cylinder by variational multi-scale large-eddy simulation [PDF]
, 2007 The aim of the present work is to validate and investigate the behaviour of a Variational Multiscale formulation (VMS) in the Large Eddy Simulation (LES) of the flow around a circular cylinder at Reynolds number, based on the free-stream velocity and on ...

Large‐eddy simulations of Hector the convector making the stratosphere wetter
, 2015 A large‐eddy simulation (LES) was performed for a Hector thunderstorm observed on 30 November 2005 over the Tiwi Islands. On that day, ice particles reaching 19‐km altitude were measured.

Analysis of Compound Open Channel Flow Using Large Eddy Simulation (LES)
Ecology and Resilient Infrastructure, 2017 본 연구는 OpenFOAM의 large eddy simulation (LES)를 이용하여 복단면 흐름을 분석하였다. LES는 여과된 연속방정식과 운동량 방정식을 수치적으로 해석하였다. 일방정식 LES와 비균일 격자를 적용하여 벽 부근의 난류 비등방성과 이차류를 재현하였다. 복단면 개수로 난류의 LES 결과는 홍수터의 수심이 깊은 경우와 얕은 경우에 대해서 제시하였다. 이들 결과는 실험 결과와 비교하였으며 실험결과와 계산 결과는 부합되는 양상을 보여준다. 또한 이차류를 생성하는 난류 비등방성의 역할에 대해서 제시하고 있다.

LARGE-EDDY SIMULATIONS OF PARTICLE-LADEN TURBULENT JETS
TASK Quarterly, 2012 The work presents an application of Large-Eddy Simulation (LES) for turbulent two-phase flows with dispersed particles. For the simulations of the continuous phase (fluid), an academic, finite volume LES solver was applied and customised. For comparison

Large Eddy Simulations of the ignition sequence of an annular multiple-injector combustor
, 2015 The ignition transient is a critical fundamental phase in combustion systems that has strong practical implications. While this phenomenon has been extensively studied on single injector configurations, the burner-to-burner propagation of a full annular ...

A Library for Wall-Modelled Large-Eddy Simulation Based on OpenFOAM Technology
, 2018 This work presents a feature-rich open-source library for wall-modelled large-eddy simulation (WMLES), which is a turbulence modelling approach that reduces the computational cost of traditional (wall-resolved) LES by introducing special treatment of the

Coherent structures in fully-developed pipe turbulence [PDF]
, 2009 A turbulent mean profile for pipe flow is prescribed which closely matches experimental observations. The nature of perturbations superimposed upon this profile is then considered.
