Critical magnetic Reynolds number of the weakly-collisional turbulent dynamo in supersonic plasmas
Radhika Achikanath Chirakkara, Christoph Federrath
Weakly-collisional plasmas are found in several turbulent astrophysical environments, such as the Intra-galaxy-cluster medium (ICM) and the solar wind, where magnetic fields can be…
Mach-number-dependent dissipative anomaly in isothermal compressible turbulence
Shadab Alam, Georgy Zinchenko, Christoph Federrath +1
Using a comprehensive set of three-dimensional, high-resolution direct numerical simulations, we investigate the existence of a dissipative anomaly in isothermal, homogeneous, isot…
The statistics and structure of dissipation in subsonic and supersonic turbulence
Edward Troccoli, Christoph Federrath
Turbulence plays a critical role in the atmosphere, oceans, engineering, and astrophysics. The dissipation (heating) induced by turbulent flows is particularly important for the th…
Transition to dilatation-dominated isothermal compressible turbulence
Shadab Alam, Christoph Federrath, Jörg Schumacher
The kinetic energy dissipation rate is of central importance for small-scale statistics in turbulent flows. Here, we report a transition to the dilatation-dominated regime of three…
