Fig. 5.

Energy spectrum for monodisperse spinners from simulations. Shown are spectra for spinners of lengths $L_s/\sigma =\mathrm{\hspace{0.17em}3}$, $4$, and $6$ at the spinner packing fraction ${\varphi }_s=\mathrm{\hspace{0.17em}0.113}$. In all cases, the Reynolds number is $Re\approx \mathrm{\hspace{0.17em}38}$. The top and bottom curves are shifted vertically by a constant factor with respect to the middle curve, for better distinction.
