Abstract / Description of output

The focus of this research is to develop a measurement instrument to characterize complex flows at spatial and temporal resolutions pertinent to understanding hydrodynamic loads in zones of fluid-structure interaction. Foundational work has demonstrated that flow velocities can be measured at a fixed focal point using a convergent array of acoustic Doppler profiling (C-ADP) instruments. As an extension of this concept, the following approach describes an application of the technology to facilitate 3D velocity measurements at a dynamically adjustable focal point location. Furthermore, the ability to dynamically control the focal point location in real-time allows the instrument to survey velocities within a three-dimensional velocity field. The resulting configuration targets a combination of measurement fidelity and control that has not been achieved by existing remote flow measurement instrumentation in the marine environment.
