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…
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…
ACES: The Magnetic Field in Large Filaments in the Galactic Center
Dylan M. Paré, Zi-Xuan Feng, Yue Hu +33
The Galactic Center (GC) is an extreme region of the Milky Way that is host to a complex set of thermal and non-thermal structures. In particular, the GC contains high-density gas…
Mitigating numerical dissipation in simulations of subsonic turbulent flows
James Watt, Christoph Federrath, Claudius Birke +1
Magnetohydrodynamic (MHD) simulations of subsonic (Mach number~) turbulence are crucial to our understanding of several processes including oceanic and atmospheric flows, the a…
Conservation of magnetic-helicity fluctuations due to spatial decorrelation of fluxes in decaying MHD turbulence
Justin Kin Jun Hew, David N. Hosking, Christoph Federrath +2
Hosking & Schekochihin (2021, Phys. Rev. X 11, 041005) have proposed that statistically isotropic decaying MHD turbulence without net magnetic helicity conserves the mean square fl…
Statistical properties of compressible isothermal turbulence from sub- to supersonic conditions
F. Thiesset, C. Federrath
This paper investigates the statistical properties of isothermal turbulence in both the subsonic and supersonic regimes. The focus is on the influence of the Mach number () and…
