What is Analytical Description of the Complete Two-dimensional Turbulent Boundary-layer Velocity Profile about?

A single analytical expression is derived for the entire (0 <or = y <infinity) velocity distribution in a two-dimensional, turbulent boundary layer on a smooth impermeable wall. The analytical expression is a linear combination of two trigonometric functions, and the expression depends on the local parameters of skin friction, shape factor, and Reynolds number based on momentum thickness. One of the trigonometric functions is an analytical solution of the continuity, momentum, and turbulent kinetic energy equations in the inner region of the boundary layer and it depends on the inner variable y+. The other trigonometric function is an empirically derived function for the outer region and it depends on the outer variable y/theta. The analytical result is validated by numerous comparisons with experimental data which include boundary layers near separation, a reattached boundary layer, nonequilibrium boundary layers, and compressible boundary layers.
