Book Description
An experimental investigation of low speed pipe flow was conducted for an initially turbulent flow of air. At subcritical Reynolds numbers, as the fluid travelled downstream its velocity profile approached the parabolic distribution corresponding to laminar flow; the rate of transition towards laminar flow being more rapid at lower Reynolds numbers. Concurrent hot-wire-anemometer measurements showed a corresponding dependence on Reynolds number of the rate of decay of the longitudinal velocity fluctuations. These velocity fluctuations were also found to decay more rapidly near the wall and center of the pipe than at intermediate radii. The energy spectrum of the fluctuations was measured along the pipe centerline, and, in terms of the macroscale, these spectra were similar. (Author).

Book Description
The report gives the results of an experimental investigation of the pressure fluctuations associated with turbulent flow in a rigid pipe. Measurements were made of the power-spectral and cross-spectral densities of the pressure fluctuations on the pipe wall for fully developed turbulent air flow over a Reynolds number range of approximately 20 to 1. The variation in Reynolds number was achieved by variation in flow velocity. The spectral content of the pressure field was investigated for frequency components from 10 to 10,000 Hz. Special attention was given to obtaining spectral levels for the low-frequency components of the pressure field because power spectral density in the low wave-number region for turbulent pipe flow is still uncertain.
