IMPLICIT LARGE EDDY SIMULATION OF INCOMPRESSIBLE FLOW
Description (Dublin Core)
eng
In a prepared urban scale model of airflow within a complex geometry area the method of Implicit Large Eddy
Simulation (ILES) is used. A staggered grid is used for a discretization of the equations describing the incompressible flow. The use of ILES comes from an application of the high resolution method for convective (advection) terms of the momentum equation. To assess the applicability of the ILES method for this purpose, we are in the stage of testing it on simple and well described cases of
turbulent flows. The first example of 3D turbulent flow is the Taylor-Green vortex – originally a simple free flow containing organized vortices with a subsequent transition to turbulence. In this contribution there will be shown several characteristics of the
turbulent flow and given their comparison with results described in literature (energy spectra, kinetic energy dissipation rate etc.).
