Taking control of compressible modes: bulk viscosity and the turbulent dynamo
James R. Beattie, Christoph Federrath, Neco Kriel +2
Many polyatomic astrophysical plasmas are compressible and out of chemical and thermal equilibrium, introducing a bulk viscosity into the plasma via the internal degrees of freedom…
Fundamental MHD scales -- II: the kinematic phase of the supersonic small-scale dynamo
Neco Kriel, James R. Beattie, Christoph Federrath +2
Many astrophysical small-scale dynamos (SSDs) amplify weak magnetic fields via highly compressible, supersonic turbulence, but established SSD theories have overlooked these compre…
Strongly stable dual-pairing summation by parts finite difference schemes for the vector invariant nonlinear shallow water equations -- I: Numerical scheme and validation on the plane
Justin Kin Jun Hew, Kenneth Duru, Stephen Roberts +2
We present an energy/entropy stable and high order accurate finite difference (FD) method for solving the nonlinear (rotating) shallow water equations (SWEs) in vector invariant fo…
Spatiotemporal dynamics of transonic shock-wave/turbulent-boundary-layer interactions in an overexpanded planar nozzle
Justin Kin Jun Hew, Emanuele Martelli, Mahdi Davoodianidalik +3
We perform a combined numerical and experimental study to investigate the transonic shock-wave/turbulent-boundary-layer interactions (STBLI) in a shock-induced separated subscale p…
Lagrangian statistics of a shock-driven turbulent dynamo in decaying turbulence
Justin Kin Jun Hew, Christoph Federrath
Small-scale fluctuating magnetic fields of order G are observed in supernova shocks and galaxy clusters, where its amplification is likely caused by the Biermann battery mechani…
