What is the Strouhal number of turbulence driven by supernovae?
Supernova-driven turbulence has a Strouhal number of about 0.25 on outer scales, with St = 1 emerging near the cooling-radius injection scale.

Scale-dependent alignment in compressible magnetohydrodynamic turbulence
Scale-dependent alignment is how turbulence connects to reconnection. We show that the nature of scale-dependent alignment in compressible turbulence differs from well-established incompressible theory.

Density FluctuationâMach Number Scaling in Compressible, High Plasma Beta Turbulence: In Situ Space Observations and High-Reynolds Number Simulations
We compare in situ space observations of Earth's magnetosheath with high resolution data showing that the density fluctuations follow a linear relation with Mach number in both.
