Conclusions and remarks

Abstract

There are several famous quotes on turbulence which describe the difficulty to treat mathematically this problem but, the following two are particularly effective. While, on one hand, Richard Feynman used to say “Turbulence is the most important unsolved problem of classical physics.” Horace Lamb, on the other hand, asserted “I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am rather optimistic.”.
