Development and Deployment of High-Speed Velocimetry for Naval Hydrodynamics and Hydroacoustics
Abstract
This project aims to advance velocimetry techniques to high spatial and temporal resolution for flow configurations of relevance to naval hydrodynamics and hydroacoustics and deploy them insituat the Carderock Division of the Naval Surface Warfare Center (NSWCCD). The data are intended to infer complex transient phenomena and validate numerical models used by NSWCCDengineers as well as collaborate with them on novel experimental techniques. Specifically, two facilities are considered to study complex flows of great importance to the naval hydrodynamic and hydroacoustic community. The NSWCCDs anechoic flow facility will be instrumented with high-repetition rate seedless velocimetry techniques to relate acoustic strength to flowdisturbances. The NSWCCDs 36 water tunnel will be instrumented with high-speed PIV and extension to volumetric measurements to study cavitation inception in a generic ducted propulsorTo date, no turn-key systems from commercial vendors can accomplish the proposed tasks. Asignificant effort will be expanded in further developing the diagnostics and prepare them for deployment at NSWCCD.
