Application of Large Eddy Simulation in the process of the Multi-Physics Field Coupling in a Combustion Chamber

MATEC Web of Conferences, 2015
Numerical simulation is the main method to solve turbulence problems. As one of the three methods which are commonly used in large-eddy simulation model (LES) is the most effective and promising research method. The basic idea of large-eddy simulation is

Industrial scale Large Eddy Simulations with adaptive octree meshes using immersogeometric analysis [PDF]

Computers & Mathematics with Applications, 2021
We present a variant of the immersed boundary method integrated with octree meshes for highly efficient and accurate Large-Eddy Simulations (LES) of flows around complex geometries. We demonstrate the scalability of the proposed method up to $\mathcal{O}(32K)$ processors.

A Coupled LES-Synthetic Turbulence Method for Jet Noise Prediction

Aerospace, 2022
Large-eddy simulation (LES)-based jet noise predictions do not resolve the entire broadband noise spectra, often under-predicting high frequencies that correspond to un-resolved small-scale turbulence. The coupled LES-synthetic turbulence (CLST) model is

Assessment of the IDDES method acting as wall-modeled LES in the simulation of spatially developing supersonic flat plate boundary layers

Engineering Applications of Computational Fluid Mechanics, 2018
The widely used improved delayed detached eddy simulation (IDDES) method is supposed to accurately predict the mean skin friction when it acts as wall-modeled large eddy simulation (WMLES), as claimed by the original authors.

Reynolds stress constrained large eddy simulation of separation flows in a U-duct

Propulsion and Power Research, 2014
This paper presents Reynolds stress constrained large eddy simulation (RSC-LES) method applied to a U-duct flow. Different from traditional Reynolds-averaged Navier-Stokes/detached eddy simulation (RANS/DES) hybrid method (including DES method), the RSC ...
