摘要：
A careful data analysis of far downstream turbulent flows generated by conventional and multiscale grids shows that these decaying flows are very clearly different from both Saffman and Loitsyansky turbulence. The analysis also shows that there are marked differences between the far downstream turbulence behaviours generated by different types of grid. There is an inflow condition dependence on both the normalised energy dissipation and the conserved large-scale invariant. (C) 2011 Elsevier B.V. All rights reserved.
