Abstract
Experiments and direct numerical simulations reveal the coexistence of two cascades in two-dimensional grid turbulence. Several features of this flow such as the energy density and the scalar spectra are found to be consistent with well known theoretical predictions. The energy transfer function displays the expected upscale energy transfers. The vorticity correlation function is logarithmic and thus consistent with recently proposed models.Keywords
