What is the Strouhal number of turbulence driven by supernovae?

James R. Beattie, Isabelle Connor, Enrico Ramirez-Ruiz

The Strouhal number, $\mathrm{St}=t_{\mathrm{cor}}/t_{\mathrm{out}}$, measures the temporal coherence of turbulent driving relative to the outer-scale eddy turnover time. In turbulence-box mod…
