Implicit Large Eddy Simulation
2007The numerical simulation of turbulent flows is a subject of great practical importance to scientists and engineers. The difficulty in achieving predictive simulations is perhaps best illustrated by the wide range of approaches that have been developed and are still being used by the turbulence modeling community.

Large eddy simulations without explicit eddy viscosity models
International Journal of Computational Fluid Dynamics, 2010The classical approach to performing large eddy simulations of turbulent flows is to employ in the governing equations subgrid scale models based on eddy viscosity concepts. The development of the similarity model about 30 years ago led to the realisation that subgrid scale models that do not use eddy viscosity concepts are possible and have many ...

Large-Eddy-Simulation (LES) Analysis
2016Computational Fluid Dynamics, usually abbreviated as CFD, has become a “third” approach in addition to the classic analytical treatment and the experimental investigation of flow and heat transfer phenomena. CFD is a branch of fluid mechanics that uses numerical methods and mathematical algorithms to solve and analyze problems that involve flow ...

Large-Eddy Simulation for Acoustics
2007Noise pollution around airports, trains, and industries increasingly attracts environmental concern and regulation. Designers and researchers have intensified the use of large-eddy simulation (LES) for noise reduced industrial design and acoustical research.

Large-Eddy Simulations of Hydrocyclones
2023This dissertation investigates the flow physics, turbulence structure, and particle classification process in hydrocyclones using large-eddy simulations of turbulent multiphase flow. Two types of hydrocyclones are considered. The first is a classifying hydrocyclone, and the second is a mineral flotation hydrocyclone, also known as an air-sparged ...
