✦ Synopsis

Harris, and Corrsin ( 2 ) have measured turbulence properties in a nearly homogeneous shear flow where far downstream of a shear-turbulence generator, the turbulence has reached a nearly homogeneous asymptotic condition with constant values of the mean velocity gradient and the one-point turbulence moments. The present note interprets the experimental results in terms of Phillips' hypothesis. The experimentally measured value of the eddy viscosity ve is found to be 0.0144 sq. ft./sec. The Eulerian space-time correlation of the axial velocity fluctuations in the apparent convective frame was fit with an exponential curve. The convective integral scale L, was then read as the value of 7 where the peak correlations dropped to the value of We. This pro-
