Experimental flow data from co-located Single beam Acoustic Doppler Profiler and Acoustic Doppler Velocimeter in the FloWave Ocean Energy Research Facility

Dataset

Abstract

Acoustic Doppler Profilers (ADPs) are routinely used to measure flow velocity in the ocean, enabling multi-points measurement along a profile while Acoustic Doppler Velocimeters (ADVs) are laboratory instruments that provide very precise point velocity measurement.
The experimental set-up allows laboratory comparison of measurement from those two instruments. Simultaneous multi-point measurements of velocity along the horizontal tank profile from Single-Beam Acoustic Doppler Profiler (SB-ADP) were compared against multiple co-located point measurements from an ADV. The data-set of this first time comparison has been made available. Measurements were performed in the FloWave Ocean Energy Research Facility at the University of Edinburgh at flow velocities between 0.6~m/s and 1.2~m/s. This data-set contains a) time series of raw SB-ADP uni-directional velocity measurements along a 10~m tank profile binned into 54 measurements cells and b) ADV point measurements of three-directional velocity time series recorded in beam coordinates at selected locations along the profile. Associated with the velocity data are instrument generated quality data, metadata and user-derived quality flags. This data-set provides multiple contemporaneous velocity measurements along the tank profile, relevant for correlation statistics, length-scale calculations and validation of numerical models simulating flow hydrodynamics in circular test facilities.
