The velocity field of the large-scale circulations (LSC) in turbulent mixed convection is analyzed by means of 2D2C particle image velocimetry (PIV). The experiments are carried out in a small-scale model room resampling a generic passenger cabin. Three different LSCs have been found, depending on the Archimedes number Ar.
