Abstract : Data on velocity fluctuations in the boundary layer on a submarine were collected and investigated. The report determines a response function for the pitot tube measuring system employed on the submarine and uses it in the analysis of some of the data. Scale and intensity of the turbulence is investigated. Velocity fluctuations within the boundary layer are found to be random with no apparent periodicity at frequencies capable of detection by the measuring system. Limitations in the determination of turbulence from the submarine data are discussed. (Author)
