The physics of turbulent, multiphase gas: Max Gronke

The physics of turbulent, multiphase gas

Max Gronke (Max Planck Institute for Astrophysics, Germany)

Many astrophysical systems such as the interstellar, circumgalactic or intracluster media are multiphase, that is, a much colder gas phase is embedded in a larger, volume filling hot phase. This structure is very hard to model and in fact leads to usually unconverged large scale (cosmological) simulations. In my talk, I want to dive into the physics of multiphase gas, and focus on questions such as what is setting the mass transfer rate between the phases, and what sets the structure and kinematics of the cold gas — which is usually observed. I will show results from high-resolution hydrodynamical simulations and analytic models which are partially inspired from the completely different field of turbulent combustion.
