Isotropic Turbulence Data

$$Re_\lambda = 315,\,$$forced, time-resolved

Energy-eddies at 4 scales.
Isocontours of high kinetic energy based on the bandpass-filtered velocities at 4
different scales $$\Delta$$ for the same instant. $$\Delta$$ expressed in terms of the Kolmogorov
length scale η. Forced isotropic turbulence, $$Re_\lambda = 315$$, $$k_{\text{max}}\eta = 2$$, $$1024^3$$ grid.
