Abstract
Measurements of the streamwise development of a variety of velocity correlations in a uniform shear flow are given and discussed. It is concluded that, in the region in which the Reynolds stresses are approximately constant, the turbulence structure is practically independent of all the initial conditions except the initial length scale. It appears that the preferential amplification of some eddy structures by the mean shear effectively destroys information about the initial conditions, apart from the initial length scale, after a total strain of about 1.5.
