Abstract
We investigate the streamwise evolutions of energy and pressure spectra along the shear-layer region of very near-field grid-generated turbulence. The energy and pressure spectra evolve significantly in this near-field. The shear-layer and vortex-shedding frequencies appear immediately in different spectra but the shear-layer's spectral signature is very soon replaced by a broad power-law spectrum on both sides of that frequency. The spectra evolve further by filling the gap between the vortex shedding and the shear-layer frequencies eventually leading to near power-law energy spectra at the point on the shear-layer region where the turbulence intensity reaches a maximum. The pressure spectrum reaches a power-law shape significantly further downstream. These spectral scalings cover a range between the vortex-shedding frequency and frequencies larger than the shear-layer frequency. They are discussed in relation to turbulent coherent structures of various sizes, obtained by using Gaussian low-pass filtering of instantaneous turbulent flow fields. High enstrophy small-scale structures originate from the shear-layer instability whereas low enstrophy large-scale structures originate from the vortex shedding. The generation of near-field energy and pressure spectra involves cooperative interactions between these two different size structures.
