EPJ E – Turbulent convection at the core of fluid dynamics

Buoyant convection of a fluid subjected to thermal differences is a classical problem in fluid dynamics. Its importance is compounded by its relevance to many natural and technological phenomena. For example, in the Earth atmosphere, the study of thermal convection allows us to do weather forecasts and, on larger time and length-scales, climate calculations. In the oceans, where there are differences in temperature and salinity, turbulent convection drives deep-water currents. Geology and astrophysics are other areas where thermal convection has great impact. The simplest and most useful convection systems is the Rayleigh-Bénard setup: a fluid in a container heated from below and cooled from above. In this classical system, the flow properties are determined by the scale and geometry of the container, the material properties of the fluid, and the temperature difference between top and bottom. The crux of the problem is to how to determine the rate of heat transfer in a given condition.

In this EPJE Colloquium paper, Francesca Chilla’ and Joerg Schumacher review the recent experimental, numerical and theoretical advances in turbulent Rayleigh-Bénard convection. Particular emphasis is given to the physics and structure of the thermal and velocity boundary layers, which play a crucial role in governing the turbulent transport of heat and momentum in highly turbulent regimes. The authors moreover discuss some important extensions of Rayleigh-Bénard convection, such as the so-called non-Oberbeck-Boussinesq effects and address convection with phase changes.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
