SUMMARY:P19 - DNS of Strongly Turbulent Thermal Convection in a Non-Rotati
 ng Full Sphere
DESCRIPTION:Poster\n\nTobias Sternberg, Philippe Marti, Giacomo Gastiglion
 i, and Andrew Jackson (ETH Zurich)\n\nBody forces such as gravity can driv
 e convective motion in fluids. Convection due to thermal gradients and the
  resulting buoyancy force is called thermal convection and occurs ubiquito
 usly in nature. We present results on DNS of thermal convection in a non-r
 otating full sphere and with different boundary conditions, the Rayleigh a
 nd Prandtl numbers being the non-dimensional control parameters. We aim to
  characterise fluid flow and heat transfer in a wide range of parameters, 
 using a global Reynolds number as a measure for the vigour of the flow and
  the Nusselt number quantifying the strength of heat advection as primary 
 diagnostics. DNS are run up to a Rayleigh number appr. 10^8 times the crit
 ical Rayleigh at a Prandtl number of unity, yielding scaling relations bet
 ween the diagnostics and Ra up to this regime of strong turbulence. The si
 mulations were performed using the fully spectral, efficiently parallelise
 d MHD/fluid dynamics code QuICC on CSCS's Daint cluster.
