    <description descriptionType="Abstract">&lt;p&gt;Conference (Lecture):&lt;/p&gt;

&lt;p&gt;American Physics Society (APS) DFD meeting 2019 Seattle&lt;/p&gt;

&lt;p&gt;In the presented Rayleigh-B&amp;eacute;nard convection experiments the turbulent 3d-&lt;br&gt;
flow of the liquid gallium-indium-tin alloy is investigated by use of ultrasound&lt;br&gt;
Doppler velocimetry, temperature and contactless inductive flow tomography&lt;br&gt;
measurements. We reconstruct for the first time near-wall as well as bulk&lt;br&gt;
flow, momentum and heat transport as well as long-term behaviour of the large-scale liquid&lt;br&gt;
metal flow at a low Prandtl number of 0.029 and high Rayleigh numbers up&lt;br&gt;
to 6 &amp;middot; 10e7. Also the influence of a strong magnetic field on the turbulent liquid metal is investigated. The results of the&lt;br&gt;
experiments are compared to direct numerical simulations and other experiments. These are also&lt;br&gt;
considered for the interpretation of the measured turbulence statistics.&lt;br&gt;
Our experiments aim to provide a deeper understanding of the turbulent&lt;br&gt;
convection and its interaction with magnetic fields in turbulent low Prandtl number&lt;br&gt;
flows as those in molten steel, aluminium or geo- and astrophysical flows.&lt;/p&gt;
