Large Eddy Simulation of Turbulent Flows Using the Lattice Boltzmann Method

Abstract

Turbulent flow is a complex fluid phenomenon because of its disordered and chaotic flow patterns. Analysis of such flows presents practical significance and is widely performed using either experiments or simulations. The numerical simulation, or computational fluid dynamics (CFD) is one powerful technique; traditionally, it is based on the Navier-Stokes equations. A novel numerical approach called the lattice Boltzmann method (LBM) has developed quickly over the past decades, and this method is based on an entirely different mechanism. The current thesis seeks to present an investigation of turbulent flows that was performed using the LBM.
