Abstract:

This report describes the final results of an experimental program conducted in the High-Speed Water Tunnel of the California Institute of Technology. The purpose of the investigation was to determine the feasibility of measuring hydrodynamic radiated noise in the water tunnel, and to measure the radiated noise for several simple flow geometries. The final report is divided into two parts, of which this is the first. It presents the results of noise measurements on fully wetted turbulent boundary layer flows. Part 2 will be concerned with measurements on cavitating flows. The noise intensity is much less in fully wetted flows than in cavitating flows, and hence the measurements described in Part 1 were much more difficult to make.
