Date of Summary | September 30, 1982 |
Subject | Attenuating Surface Waves in a Localized Region of the Open Ocean |
Performing Activity | Stevens Institute of Technology |
Principal Investigator | Dr. R. I. Hires |
Contracting Agency | Office of Naval Research |
Completion | Complete |
Description | This was an experimental investigation of the refraction of surface waves from a localized area of the open ocean for purposes of launching and retrieving divers and submersibles as well as smoothing water where divers are working. |
Progress | Complete. Towing tank experiments were conducted in regular, oblique, and random waves using towed turbulence grids. For regular waves, dramatic wave attenuation can be obtained at modest power requirements for wave periods up to six seconds. Results for oblique and random seas require much more power, but are still encouraging. Full scale trials were conducted revealing wave attenuation, but because of fairly calm seas, tests should be rerun, at quarter scale. |
