Isotropic analysis of grid-turbulence
The principles of self-similar isotropic turbulence are applied to the analysis of grid-decay. In particular it is theoretically established that energy-transfer occurs in only two distinct invariant modes. The decay constant of third-order correlations is posed in terms of the "amounts" of each mode present in the decay. This constant is determined empirically, and is found to be relatively insensitive to changes in Re. The related decay of turbulence intensity is computed. © 1989.
