Abstract
The clusterization and amplitude intermittency of temperature fluctuations in turbulent convection were investigated. The temperature time traces were obtained in turbulent thermal convection at high Rayleigh numbers. A telegraph approximation for temperature traces were generated by setting the fluctuation amplitudes to 1 or 0, which allowed to distinguish the tendency of events to cluster from their large-scale variability in amplitude. The telegraphic approximation is useful because of the specific process of heat transfer, which was determined in large measures by the random motion of temperature plumes.
