  The modified Townsend-Perry attached eddy model of Vassilicos et al (2015)
combines the outer peak/plateau behaviour of rms streamwise turbulence velocity
profiles and the Townsend-Perry log-decay of these profiles at higher distances
from the wall. This model was validated by these authors for high Reynolds
number tur- bulent pipe flow data and is shown here to describe equally well
and with about the same parameter values turbulent boundary layer flow data
from four different facilities and a wide range of Reynolds numbers. The model
has predictive value as, when extrapolated to the extremely high Reynolds
numbers of the SLTEST data obtained at the Great Salt Lake Desert atmospheric
test facility, it matches these data quite well.
