Abstract
We report on temperature oscillations which we observed during experiments in turbulent mixed convection in a rectangular enclosure. We ascribe these temperature fluctuations to oscillations and spontaneous reorientations of the large scale circulations in the flow. Stable temperature configurations, periodic oscillations as well as spontaneous reversals and reorientations were detected. Comparison with smoke visualisations allowed to assign the observed temperature distributions to a certain number and configuration of convection rolls.
