Adaptively Refined Large-Eddy Simulations of Galaxy Clusters

Adaptiv verfeinerte Grobstruktursimulationen von Galaxienhaufen

Please always quote using this URN: urn:nbn:de:bvb:20-opus-32274
  • It is aim of this work to develop, implement, and apply a new numerical scheme for modeling turbulent, multiphase astrophysical flows such as galaxy cluster cores and star forming regions. The method combines the capabilities of adaptive mesh refinement (AMR) and large-eddy simulations (LES) to capture localized features and to represent unresolved turbulence, respectively; it will be referred to as Fluid mEchanics with Adaptively Refined Large-Eddy SimulationS or FEARLESS.
  • Ziel dieser Arbeit war, ein neues numerisches Modell zu entwickeln, welches es ermöglicht Grobstruktursimulationen auch mit adaptiven Gittercodes auszuführen, um Turbulenz über große Längenskalenbereiche konsistent zu simulieren.
