Journal ArticleDOI
A numerical method for large-eddy simulation in complex geometries
TL;DR: In this article, the authors discuss the development of a numerical algorithm and solver capable of performing large-eddy simulation in very complex geometries often encountered in industrial applications, such as unstructured hybrid grids.
Journal ArticleDOI
Numerical investigations of flow over a sphere in the subcritical and supercritical regimes
TL;DR: In this paper, the Strouhal number, St, associated with large-scale shedding is predicted at St∼0.195 along with a higher frequency component associated with the development of the Kelvin-Helmholtz instabilities in the detached shear layers.
Journal ArticleDOI
Structure of turbulent flow at a river confluence with momentum and velocity ratios close to 1: Insight provided by an eddy‐resolving numerical simulation
George Constantinescu,Shinjiro Miyawaki,Bruce L. Rhoads,Alexander Sukhodolov,Gokhan Kirkil,Gokhan Kirkil +5 more
TL;DR: In this paper, an eddy-resolving numerical model was used to simulate the mean flow and large-scale turbulence structure at an asymmetrical river confluence with a concordant bed when the momentum ratio between the two incoming streams is close to 1.
Journal ArticleDOI
LES and DES Investigations of Turbulent Flow over a Sphere at Re = 10,000
TL;DR: In this paper, Germano et al. used a dynamic Smagorinsky type subgridstress (SGS) model and Detached Eddy Simulation (DES) to simulate the flow around a sphere at a Reynoldsnumber of 104 in the subcritical regime.
Book ChapterDOI
A numerical method for large-eddy simulation in complex geometries
TL;DR: This chapter discusses the development of a numerical algorithm and solver capable of performing large-eddy simulation (LES) in geometries as complex as the combustor of a gas-turbine engine.
