Abstract : By direct numerical simulations, we show that there exists the hierarchy of vortex axes in turbulence, which is self-similar in a wide range of scales, i.e., in the inertial range and a lower part of the dissipation range. This result means that the volume fraction occupied by the tubular vortices at each scale is independent of the scale.
