Special attention has been focused on dissipation and non-equilibrium characteristics in the decay region. A wide non-equilibrium region is observed for fractal square grids with three and four iterations. The distributions of the Taylor microscale \u03bb, integral length scale Lu, and dissipation coefficient C\u03b5 show that a simple combination of large and small grids does not reproduce elongated non-equilibrium regions as realized by the fractal square grid. On the other hand, a new kind of grid, quasi-fractal grids, in which the region of the smaller fractal elements (N=2\u20134) of the fractal square grid is replaced by regular grids, successfully reproduce a similar flow field and non-equilibrium nature to that seen in the fractal square grid case. This suggests that the combination of large square grid and inhomogeneously arranged smaller grids produces an elongated non-equilibrium region. The dissipation coefficient C\u03b5 is better collapsed using Re0=t0U\u221e/\u03bd (where t0 is the thickness of the largest grid bar, U\u221e the inflow velocity, and \u03bd the kinematic viscosity) as a global/inlet Reynolds number rather than ReM=MU\u221e/\u03bd (where M is the mesh size) [P.
