Large Eddy Simulation (LES) with a Dynamic Subgrid-scale Model (DSM) is a powerful tool to predict natural convection in a room. However, the model needs to calculate the average of the model coefficient over a homogeneous direction. Since most natural convection flow in a room does not have a homogeneous direction, this study proposes a new Filtered Dynamic Subgrid-scale Model (FDSM) without the need of a homogeneous flow direction. Our calculation based on air velocity, air temperature and turbulence distributions agree reasonably well with the previous experimental data. The results show that the FDSM can be used to simulate natural convection in a room.
