We reconstruct for the first time near-wall as well as bulk<br>\nflow, momentum and heat transport as well as long-term behaviour of the large-scale liquid<br>\nmetal flow at a low Prandtl number of 0.029 and high Rayleigh numbers up<br>\nto 6 · 10e7. Also the influence of a strong magnetic field on the turbulent liquid metal is investigated. The results of the<br>\nexperiments are compared to direct numerical simulations and other experiments. These are also<br>\nconsidered for the interpretation of the measured turbulence statistics.<br>\nOur experiments aim to provide a deeper understanding of the turbulent<br>\nconvection and its interaction with magnetic fields in turbulent low Prandtl number<br>\nflows as those in molten steel, aluminium or geo- and astrophysical flows.</p>\n\n<p> </p>", "@id": "https://doi.org/10.14278/rodare.232", "creator": [ { "name": "Schindler, Felix", "@type": "Person" }, { "name": "Z\u00fcrner, Till", "@type": "Person" }, { "name": "Vogt, Tobias", "@id": "https://orcid.org/0000-0002-0022-5758", "@type": "Person" }, { "name": "Eckert, Sven", "@id": "https://orcid.org/0000-0003-1639-5417", "@type": "Person" }, { "name": "Schumacher, J\u00f6rg", "@type": "Person" } ], "name": "Rayleigh-B\u00e9nard Convection in Liquid metal under Influence of Vertical Magnetic Fields", "identifier": "https://doi.org/10.14278/rodare.232", "inLanguage": { "name": "English", "@type": "Language", "alternateName": "eng" }, "sameAs": [ "https://www.hzdr.de/publications/Publ-30444" ], "version": "V1.1", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "keywords": [ "Rayleigh-B\u00e9nard convection", "magnetohydrodynamics", "low Prandtl number", "liquid metal", "ultrasound velocimetry" ], "url": "https://rodare.hzdr.de/record/232" }
