1. mmu.VELOCITY Thc failure of thc data 10 collapse into a single line is plotted in figures 19-22 suggest a more detailed Analysis is in order. In reference 10 Lighthill has derived the integrated equations for a laminar boundary under the assumptions of a constant phase excitation.' The general equation is not restricted lo laminar flow until laminar profiles are inserted into the several terms. i.e. for the mean displacement thickness (8').
