Abstract : Two integral theories for compressible flow are derived from the calculation of pressure on a perturbed plane wall in the presence of viscous boundary layer. A simple theory is derived from the von Karman momentum integral equation, and a rational theory is derived by iteration from asymptotic perturbation theory. In both theories, the wall pressure amplitude and phase angle are functions of a single similarity parameter X which is proportional to boundary layer thickness. The two theories are compared with experimental results and with numerical calculations based on asymptotic perturbation theory. Qualitative and quantitative results based on the rational integral theory are compared with experimental results. (Author)
