Abstract
Any discontinuity in flov; at a plane boundary is dispersed by the diffusion of vorticity
into a boundary layer and vyake. Experimental measurements in the past have been correlated
with empirical formulations. A generalization gives both the horizontal component and the
vertical component of the mean velocity. In the laminar sublayer the velocity is a solution
of the diffusion equation. In the turbulent boundary layer the velocity can be expressed by
a Fourier integral. In the free stream there is a vertical persistence of velocity. The
computation of velocity is provided by subroutines.
