Implicit large eddy simulation of channel and urban environment flows

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.

The paper presents implicit large eddy simulations (ILES) of low speed flows in conjunction with different computational methods raging from second to ninth order of accuracy. The simulations include channel and urban environment flows based on a model of an array of buildings. The aim of this study is to demonstrate the accuracy of several different ILES models against direct numerical simulations (DNS) and experimental data.
