Abstract : Theoretical development of a law of the wall-law of the wake, incompressible, turbulent boundary-layer calculation method was published in AD-609 989. As a follow-on, the method is used here to obtain practical boundary-layer solutions, solving the equations on a high-speed computer and comparing the theoretical calculations with experimental data. It was necessary to make several modifications to the basic method, the most important being the inclusion of a way to give the boundary-layer solution a 'memory'. The calculation method appears able to yield satisfactory engineering answers for two-dimensional and axisymmetric boundary layers that develop in pressure distributions containing regions of adverse pressure gradient, favorable pressure, and zero or nearly zero pressure gradient.
