We report on measurements of energy spectra, second and higher order structure functions in bubbly turbulence. The void fraction is up to 2.9 % with an mean equivalent bubble size of 3-5 mm. We find the results of [I. Mazzitelli, D. Lohse, F. Toschi, Phys. Fluids 15, L5 (2003)] qualitatively confirmed, i.e. a more pronounced energy enhancement on small scales than on large scales due to the presence of the bubbles, leading to a less steep slope in the spectrum as compared to the Kolmogorov -5/3 law.
