The potential of large eddy simulation techniques for modelling indoor air flows.

Large eddy simulations (LES) were performed for flows relevant to or incurred in ventilation air motions with and without thermal effects. The emphasis was placed on the discussion of the possibility and potential of LES for modelling indoor air flows. Some prospective views were given on the capability and implementation of the LES approach. LES is a potential tool for providing detailed and accurate solution of turbulent flow and heat transfer in analyses of indoor environment and building energy performance. In the foreseeable future, however, it will remain mainly as a complementary approach to statistical modelling and experiments owing to the limitation of computational costs.
