From 2D to 3D: Recovering Turbulent Density Dispersions from Noisy Data
Luz L. Jimenez Vela, Christoph Federrath, David C. Collins +1
Turbulence plays a central role in shaping the structure and dynamics of the interstellar medium (ISM), governing the star formation rate (SFR) and the initial mass function (IMF).…
Amplification of turbulence through multiple planar shocks
Michael F. Zhang, Seth Davidovits, Nathaniel J. Fisch
We study the amplification of isotropic, incompressible turbulence through multiple planar, collisional shocks, using analytical linear theory. There are two limiting cases we expl…
Turbulence Generation by Shock Interaction with a Highly Non-Uniform Medium
Seth Davidovits, Christoph Federrath, Romain Teyssier +3
An initially planar shock wave propagating into a medium of non-uniform density will be perturbed, leading to the generation of post-shock velocity perturbations. Using numerical s…
The driving mode of shock-driven turbulence
Saee Dhawalikar, Christoph Federrath, Seth Davidovits +4
Turbulence in the interstellar medium (ISM) is crucial in the process of star formation. Shocks produced by supernova explosions, jets, radiation from massive stars, or galactic sp…
Bulk hydrodynamic stability and turbulent saturation in compressing hot spots
Seth Davidovits, Nathaniel Fisch
For hot spots compressed at constant velocity, we give a hydrodynamic stability criterion that describes the expected energy behavior of non-radial hydrodynamic motion for differen…
Modeling turbulent energy behavior and sudden viscous dissipation in compressing plasma turbulence
Seth Davidovits, Nathaniel J. Fisch
We present a simple model for the turbulent kinetic energy behavior of subsonic plasma turbulence undergoing isotropic three-dimensional compression, such as may exist in various i…
Turbulent stagnation in a z-pinch plasma
E. Kroupp, E. Stambulchik, A. Starobinets +7
The ion kinetic energy in a stagnating plasma was previously determined by Kroupp et al. (Kroupp et al., 2011), from Doppler-dominated lineshapes augmented by measurements of plasm…
A lower bound on adiabatic heating of compressed turbulence for simulation and model validation
Seth Davidovits, Nathaniel J. Fisch
The energy in turbulent flow can be amplified by compression, when the compression occurs on a timescale shorter than the turbulent dissipation time. This mechanism may play a part…
Compressing turbulence and sudden viscous dissipation with compression-dependent ionization state
Seth Davidovits, Nathaniel J. Fisch
Turbulent plasma flow, amplified by rapid 3D compression, can be suddenly dissipated under continuing compression. This effect relies on the sensitivity of the plasma viscosity to…
Sudden viscous dissipation of compressing turbulence
S. Davidovits, N. J. Fisch
Compression of turbulent plasma can amplify the turbulent kinetic energy, if the compression is fast compared to the viscous dissipation time of the turbulent eddies. A sudden visc…
An Efficient Algorithm for Classical Density Functional Theory in Three Dimensions: Ionic Solutions
Matthew G. Knepley, Dmitry A. Karpeev, Seth Davidovits +2
Classical density functional theory (DFT) of fluids is a valuable tool to analyze inhomogeneous fluids. However, few numerical solution algorithms for three-dimensional systems exi…
