TEAMER

This dataset documents a series of controlled laboratory experiments conducted at the O.H. Hinsdale Wave Research Laboratory to evaluate the performance of a dual-function Oscillating Water Column (OWC) system integrated with a slotted breakwater. The experiments aimed to characterize both wave energy conversion and shoreline protection performance under a range of wave and structural configurations. The OWC array featured ten 1" thick pneumatic chambers (4'x4'x3'), each equipped with a sharp-edged orifice plate, and mounted on a slotted barrier with two tested porosities (10% and 25%). Tests were performed in a wave basin under regular, random, and obliquely incident wave conditions, across two water depths (1.22m and 1.37m).

Data collection was comprehensive, involving 24 wave gauges, 8 Acoustic Doppler Velocimeters (ADVs), 10 differential pressure sensors, 3 ultrasonic sensors, a force balance, and an anemometer. These instruments were distributed across the basin and mounted on the physical model. The dataset includes raw data, calibrated data, and post-processed outputs in multiple formats (MATLAB, ASCII text, and WaveLab-compatible files). Instrument positions, calibration metadata, and acquisition synchronization details are thoroughly documented. Units are clearly labeled, and the dataset is structured to be compatible with automated processing scripts developed at the laboratory.

Users should consult the comprehensive README.pdf found below for detailed guidance on directory structure, data formatting, instrumentation, calibration procedures, and post-processing workflows. The README also outlines proprietary software requirements (e.g., MATLAB, LabVIEW) and system-specific calibration assumptions necessary for full utilization of the dataset.

The PTO DEMO folder includes data obtained from a preliminary test power take off device, a bidirectional impulse turbine generator. The data includes and analog and digital .csv files time stamped. The PTO data is not time synchronized with the rest of the data, it is for demonstration purpose only. The analog file corresponds to the voltage out of a 36W Brushless DC motor which has been rectified and stepped down to 0-5V. The digital file corresponds to the built in hall affect sensor on the motor.
