Using large eddy simulation to study airflows in and around buildings

Submitted by admin on Sat, 07/06/2013 - 16:35

This investigation uses three subgrid-scale models of large eddy simulation (LES) to study airflows in and around buildings. They are the Smagorinsky model, a filtered dynamic subgrid-scale model, and a stimulated small-scale subgridscale model. For outdoor airflow that is highly turbulent, the simple Smagorinsky model is sufficient. For indoor airflow where laminar flow can be as important as turbulent flow, the filtered dynamic subgrid-scale model and the stimulated small-scale subgrid-scale model are recommended.
