Rayleigh-benard convection mercury
WebLa convection naturelle apparait largement dans la nature, et demeure un sujet d’intérêt majeur pour la compréhension des phénomènes géophysiques. Les écoulements qui lui sont liés sont de grande ampleur et restent difficiles à reproduire en laboratoire. Afin d'atteindre en laboratoire des régimes semblables, on se propose d'utiliser des fluides dont la … http://www.scholarpedia.org/article/Rayleigh-B%C3%A9nard_convection

Linear and weakly nonlinear stability analyses of Rayleigh–Bénard convection (RBC) in a radiating Newtonian fluid are studied in the paper. The optical properties of the Newtonian fluid are considered to be independent of the wavelength of radiation. A gray medium thus assumed allows us to consider two asymptotic cases: (a) …
WebTransient natural convective heat transfer of liquid gallium, which has a Prandtl number of 0.023 at 310 K, from a heated horizontal circular cylinder to its coaxial triangular enclosure is studied numerically by employing the control volume method. Two orientations of the triangular cylinder are investigated and the Grashof number is varied from 10 4 to 10 7. WebMar 30, 2024 · The model involves the convection of a fluid with a compositional variation making light fluid float on top of simple convection. It might be called an Occum's razor approach as it is one of the simplest of models for showing the evolution of a crust under the influence of mantle (Rayleigh-Benard) convection.
