Instantaneous velocity and temperature distribution in a room predicted by LES
Large eddy simulation (LES) could be a next-generation tool to predict airflow in and around buildings, because LES is universal, has few or no adjustable model coefficients, and can provide more flow information. We are developing different LES dynamic subgrid models that are suitable for both indoor and outdoor airflows, and advance numerical algorithm to reduce computing costs. The new models and algorithm are being applied for natural ventilation design in buildings.
