LES at Work: Quality Management in Practical Large-Eddy Simulations
2008This paper aims at reviewing some important aspects of Large Eddy Simulation (LES) as applied to engineering applications. In particular we focus on aspects relevant to quality management and validation and verification procedures. After outlining the LES formalism and the numerical methods considered appropriate for engineering applications we discuss

Large Eddy Simulation (LES) for Steady-State Turbulent Flow Prediction
2014The aim of this work is to simulate a steady turbulent flow using the Large Eddy Simulation (LES) technique in computational fluid dynamics (CFD). The simulation was done using an in-house code developed in the programming platform of Visual C++. The Finite Volume Method was used to compute numerically the solutions of the Navier-Stokes equation under ...

Parametric studies on acoustics of corrugated tubes using large eddy simulation (LES)
Noise Control Engineering Journal, 2014Airflow through a corrugated tubing can generate loud tonal sounds. The production of these tones, sometimes called as whistling, in a corrugated tubing is an interesting phenomenon because the presence of corrugations in a straight tube transforms the tube into an aerodynamic sound source that may produce significant tones and resonance responses ...

In this paper, computational fluid dynamics (CFD) viscous flow simulation of BO-105 isolated helicopter rotor blades was simulated using commercially available STAR-CCM + software. The aim of these simulations is to capture the complex flow dynamics and blade vortex interaction (BVI) noise generation in hover configuration.

A Large Eddy Simulation (LES) of Plate-Fin and Tube Heat Exchangers
2010 14th International Heat Transfer Conference, Volume 4, 2010Plate-fin and tube heat exchangers are extensively studied both experimentally and numerically. With a large eddy simulation technique (LES), this study performs a detailed investigation of the temporal oscillations of streamwise, spanwise and normal velocity components in the exchanger passage and their effects on heat transfer between fins and fluid.

Emulating Wildfire Plume Injection Using Machine Learning Trained by Large Eddy Simulation (LES)
Environmental Science & TechnologyWildfires have a major influence on the Earth system, with costly impacts on society. Despite decades of research, wildfires are still challenging to represent in air quality and chemistry-climate models. Wildfire plume rise (injection) is one of those poorly resolved processes and is also a major source of uncertainty in evaluating the wildfire ...
