AG.RBK - Rayleigh-Bénard Convection

Thermal convection is an important driving mechanism for geophysically relevant flows in the atmosphere, the oceans, the Earth's Earth's mantle, the Earth's core, and on other planets and stars. In this some basic properties of convection will be investigated. are investigated. A cube filled with water is heated from below and cooled from above. The convection motion is then characterized optically and with local local temperature probes. A numerical simulation accompanies the experiment. Results of the experiment are the qualitative shape of the motion, the formation of boundary layers, temperature and velocity profiles, as well as spectra and probability distributions of the of the temperature.
