Large eddy simulation of indoor airflow with a filtered dynamic subgrid scale model

Abstract Accurate prediction of the distributions of indoor airflow is very important for designing a comfortable and healthy indoor environment. This paper uses a large eddy simulation (LES) program with a filtered dynamic subgrid scale model to calculate natural, forced and mixed convection flows in rooms. The predicted air velocity, air temperature and turbulence distributions agree reasonably well with the corresponding experimental data. The LES has great potential for the simulation of indoor airflow.
