1.   However, as was pointed out there, the waves predicted by such theory are only the first stage of the evolution towards turbulent motion.

2.   The remainder of the transition process consists of the growth of these local regions of turbulent motion, whilst they travel downstream.

3.   A turbulent spot is essentially a localized region of fully turbulent motion.

4.   Breakdown to turbulent motion occurs.

5.   Frequent references to turbulent motion have been made in previous chapters, but detailed discussion of the nature of that motion has so far been postponed.

6.   The ideal aim of a theory of turbulent motion would be the development of a statistical mechanics analogous to those developed in the kinetic theory of gases.

7.   To illustrate how they can indicate the scale and structure of a turbulent motion, we now look at typical properties of double correlations.

8.   Another method of discovering the time scales associated with turbulent motion is, obviously, Fourier analysis.
