Influence of the inlet boundary conditions on the LES performance for the cavity flow benchmark [PDF]
E3S Web of ConferencesA cavity flow consists of one air inlet and one outlet slot. The inlet slot is positioned in the upper left corner of the cavity, whereas the outlet slot is located in the lower right. This cavity flow is representative of mixing ventilation.

Computational fluid dynamics of airflow rates for natural ventilation with opposing wind and buoyancy [PDF]
E3S Web of ConferencesWind and buoyancy both play an important role as driving forces of natural ventilation. Previous theoretical analysis has shown that there might be at most three mathematical solutions of airflow rate for a known indoor heat generation rate and wind ...

Hybrid RANS/LES applied to complex terrain
Wind Energy, 2011 AbstractLarge Eddy Simulation (LES) of the wind in complex terrain is limited by computational cost. The number of computational grid points required to resolve the near‐ground turbulent structures (eddies) are very high. The traditional solution to the problem has been to apply a wall function that accounts for the whole near‐wall region.
