# Kinematics of Homogeneous Turbulence

Chapter

## Abstract

From a mathematical standpoint, the velocity field \(\vec u\left( {\vec x,t} \right) \) will be assumed to be a random function defined on a sample space (see e.g. Papoulis, 1965). One can imagine for instance that we record the longitudinal air velocity at a given location in a wind tunnel: if the experiment is repeated N times in the same conditions, one obtains N realizations of the velocity evolution, each of them corresponding to a point in the sample space. For instance Figure V-l represents four recordings of the *u*’velocity fluctuations obtained in such an experiment.
