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-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.

Turbulence and Large-Eddy Simulations
2006After having discussed the limits of turbulence direct-numerical simulations, one presents large-eddy simulations methods, where small scales are filtered out and modelled by appropriate eddy coefficients in the evolution of large scales. We concentrate on models developed originally in Fourier space, then adapted to physical space.

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 ...
