  Fully developed turbulence is analised with the lattice model employing
vortex tube representation which is introduced recently by the authors. Several
characteric features observed in experiments and direct numeric integrations
are reproduced. Not only Kolmogorov's inertial range is observed, but also
several local probability distribution functions are obtained as well. Those of
the local velocities are close to the Gaussian and exponential-like
distributions appear in local vorticity, relative velocities and local velocity
consisting of only higher wave number components. Coherent structure of vortex
tubes is seen, too. Moreover required cpu-time and memory-size are very little
comparing with the conventional pseudo-spectral method. keywords : fluid
