Major Research Interests
Turbulent thermal convection is one of the most important heat transport mechanism and a model system for turbulence. It occurs in many geo- and astrophysical systems, such as the Earth's atmosphere, its outer core, or stellar interiors. Due to its turbulent nature no exact models exists to describe such flows and or predict the heat transport therein.
Therefore, experiments are particular important. In my work I conduct experiments to answer various questions concerning turbulent convection.
In example I study, how rotation affects the flow structure and the transported heat in thermal convection, a question most relevant for atmospheric research. Another question is, how phase transitions in the convecting fluid change the convection pattern and the heat transport.
