Description

Resent years it becomes possible to reproduce turbulent flow field in architectural aerodynamics by numerical simulation using supercomputer technology. The aim of this paper is to describe various Computer Graphics method for visualizing and analyzing the complex turbulent flow fields around buildings and in a room. The un-steady turbulent flowfield was simulated by numerically solving the filterd, three dimensional time dependent Navier-Stokes equations. Large Eddy Simulation was used for turbulent modeling. As a result of this analysis many new aspects of turbulent phenomena became clear.
