An Analytic Solution for the Boundary Layer Equations - Develops a solution for the boundary layer equations in terms of complex variables. From these, a real-valued solution is derived for the boundary layer near a flat plate, showing an exponential rise to the main flow velocity. This solution is shown to have the self-similarity property.
