Description: Any discontinuity in flow at a plane boundary is dispersed by the diffusion of vorticity into a boundary layer and wake. 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.
