Heat transport and boundary layer structure in Rayleigh-Benard convection: Many turbulent flows in nature and technology are driven by sustained temperature differences. Applications range from cooling devices of chips to convection in the Earth and
the Sun. Turbulent Rayleigh-Benard convection (RBC) is the paradigm for all these convective phenomena because it can be studied in a controlled manner, but it still has enough complexity to contain the key features of convective turbulence in the examples just mentioned. RBC in cylindrical cells has been studied intensely over the last few years in
several laboratory experiments. The key question in RBC is the mechanism of turbulent transport of heat and momentum. A deeper understanding of these mechanisms requires a detailed analysis of the dynamics of the boundary layers.
