The integral over the wavenumber space in the Hopf characteristic functional equalion is approximated by a Monte Carlo quadrature so that the continuous dynamicaldegrees of freedom may be replaced by a finite number ccf discrete ones. Thedynamics to govern the discrete variables (i.e. the sampled velcccity modes) is built insuch a way that the invariance properties of the original Navier-Stokes eq uation for incompressible inviscid flow are exactly preserved. A realization of flow based on thisdynamics gives a plausible power law of energy decay and tlte -5/3 power law ofenergy spectrum wuth a proper Kolmogorov constant fccr Reynolds numbers1 oo - 5 oo .
