Kurzfassung
We conduct Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of turbulent mixed convection in parallelepiped convective cells with heated parallelepiped obstacles inside, which represents indoor ventilation in a generic room. The considered Reynolds number Re based on the velocity of the inlet flow and the width of the inlet ducts is up to Re=1.0×10^3 (and 1.5×10^5 if based on the height of the cell) and the Grashof number Gr based on the height of the generic room and the temperature difference of the heated obstacles and the cooled inlet flows is up to Gr=2.8×10^10 . The flow for Re=1.5×10^5 , Gr=2.8×10^10 and the length of the domain L ˆ =5 m is studied by means of LES based on the Smagorinsky model. The results of the simulations reveal a strong dependency of the global flow structures on the Grashof number Gr , Archimedes number Ar and the length of the domain.
