Vortex statistics for turbulence in a container with rigid boundaries

The evolution of vortex statistics for decaying two-dimensional turbulence in a square container with rigid no-slip walls is compared with a few avail able experimental results and with the scaling theory of two-dimensional tu rbulent decay as proposed by Carnevale et al. Power-law exponents, computed from an ensemble average of several numerical runs, coincide with some exp erimentally obtained values, but not with data obtained from numerical simu lations of decaying two-dimensional turbulence with periodic boundary condi tions.
