  A composite representation of the turbulent boundary-layer velocity profile
is proposed, which combines a recently determined accurate interpolation of the
universal law of the wall with a simple analytical expression of the smooth
transition of velocity to a constant value in the outer stream. Several
examples are given of application of this representation to DNS and
experimental data from the literature, and a conjecture is offered for the
asymptotic approach of the velocity to its constant inviscid value.
