Résumé

Examines the airflows driven by a revolving door that links two rooms of initially uniform temperature. Considers two situations, the first in which the rooms are at equal temperature, and the second in which there is a temperature difference between the rooms. The flows were examined using a small-scale model of a revolving door with fresh- and salt-water solutions to represent temperature differences. The results reveal how the transfer of air across a revolving doorway depends on the rotation rate and temperature difference. Identifies rotation limited and buoyancy limited flows. Discusses implications to the design and operation of revolving doorways.
