Summary

Story summary

Kolmogorov's turbulence theory applies to gas bubbles rising in water and indicates Kolmogorov scaling for bubbles three to five millimeters in diameter.
An international team from Helmholtz-Zentrum Dresden-Rossendorf, Johns Hopkins University, and Duke University conducted 3D measurements of bubbles and surrounding fluid.
The study, published in Physical Review Letters, resolves the debate on Kolmogorov's 1941 theory for bubbly systems and could improve industrial processes and climate models.
