SOME PRACTICAL APPLICATIONS OF BOUNDARY LAYER PRESSURE FLUCTUATION WORK,

Abstract

A general description is given of some practical applications of boundary layer pressure fluctuation work and the next steps which need to be examined in the overall problem of boundary layer noise are indicated. The first problem dealt with is that of the metal fatigue of structures due to turbulent boundary layer pressure fluctuations on high speed airliners. Following this, the question of internal noise levels in the cabin is discussed and the method of calculation, or lack of method, is commented upon. The report also deals with noise radiated from the boundary layer in two specific cases: first, the radiated noise from an axial compressor and, secondly, the radiated noise from a submarine hull. The grave deficiencies in knowledge are described and experiments aimed at filling some of these gaps are outlined. (Author)
