Novel power law of turbulence spectrum

Web1 nov. 2024 · Thermal microstructure profiling is an established technique for investigating turbulent mixing and stratification in lakes and oceans. However, it provides only quasi-instantaneous, 1-D snapshots. Other approaches to measuring these phenomena exist, but each has logistic and/or quality weaknesses. Hence, turbulent mixing and stratification … Web6 mrt. 2009 · This power law spectral decay corresponds to infinite enstrophy and is …
