Hydrodynamic Studies for a Large, High-Speed, Variable Pressure, Free Surface Flow Facility,
Abstract
The naval surface ships of the future will operate at progressively greater speeds which will entail increasingly serious hydrodynamic problems. Although analytical solutions to these problems will also progress, model studies will continue to provide much of the practical understanding of new high-speed design concepts. Accordingly, the potentials of naval model test facilities must be upgraded from time to time to provide for these future needs. To this end, definitive action, based on preliminary studies which had been under way at NSRDC for several years, was begun in 1971 to determine whether existing NSRDC facilities could be satisfactorily upgraded. As part of this effort the St. Anthony Falls Hydraulic Laboratory contracted in September of 1971 for a study of the feasibility of upgrading the performance potentials of the existing 36 inch cavitation tunnel at NSRDC. This study led to a feasibility report which concluded that the 36 inch tunnel could not be practically adapted to provide the desired performance capabilities, but that these needs could probably be fulfilled by a new channel facility. An extensive model testing program was advocated to develop a design for such a facility. This report summarizes the findings of this model test program.
