Experimental data: spar-buoy OWC wave energy converter for low-power applications

This dataset supplements the manuscript with the title “Unveiling the potential of using a spar-buoy oscillating-water-column wave energy converter for low-power stand-alone applications”, Applied Energy, doi:10.1016/j.apenergy.2021.116835 The dataset includes the irregular-wave time-series that allows the reproduction of the results presented in Figs. 15, 16, 17, and 18, using a larger orifice plate (OS3). The data may be used for result reproduction, numerical modelling validation, and control purposes. We present all data at model-scale, which was 1:10th, using Froude scaling criterion. You may find data for two significant wave heights Hs [m], and for several energy periods Te [s]. Each excel file includes the time-series of the following: • the pressure difference (tab 1, column B), • the relative motion between the buoy and the oscillating-water-column (OWC) (tab 1, column C), • the free-surface-elevation as it was recorded by the wave gauge next to the buoy (tab 1, column D), • the motions in six degrees-of-freedom (tab 2). The calibrations have already been applied to the data, and all time-series have been filtered. Below you can find the number and main characteristics (sea-states) for each excel file (the significant wave height Hs [m] (rounded value) and the energy period Te [s], at model scale): Test (65): Hs = 0.1 m, Te = 1.76 s Test (66): Hs = 0.1 m, Te = 1.80 s Test (67): Hs = 0.1 m, Te = 2.02 s Test (68): Hs = 0.1 m, Te = 2.50 s Test (69): Hs = 0.1 m, Te = 3.23 s Test (70): Hs = 0.1 m, Te = 3.58 s Test (71): Hs = 0.1 m, Te = 4.88 s Test (73): Hs = 0.2 m, Te = 2.30 s Test (74): Hs = 0.2 m, Te = 2.67 s Test (75): Hs = 0.2 m, Te = 3.19 s Test (76): Hs = 0.2 m, Te = 5.02 s本数据集补充了题为《揭示柱形浮标振荡水柱（oscillating-water-column, OWC）式波浪能转换器在低功耗独立应用中的潜力》的学术论文手稿，该论文发表于《应用能源》（Applied Energy），DOI:10.1016/j.apenergy.2021.116835。 本数据集包含不规则波浪时序数据，可复现论文中图15、16、17及18中采用更大孔径板（OS3）的实验结果。本数据可用于实验结果复现、数值建模验证及控制相关研究。 所有数据均采用1:10模型尺度，遵循弗劳德相似准则（Froude scaling criterion）进行缩放。数据涵盖两种有效波高Hs [m]与多组能量周期Te [s]的工况。 每个Excel文件包含以下时序数据： • 压差（工作表1，B列） • 浮标与振荡水柱（OWC）间的相对运动（工作表1，C列） • 浮标旁波高计记录的自由表面高程（工作表1，D列） • 六自由度运动数据（工作表2） 本数据集已完成数据校准，所有时序数据均经过滤波处理。 以下为每个Excel文件对应的试验编号及其主要海况特征（模型尺度下的有效波高Hs [m]与能量周期Te [s]）： 试验65：Hs = 0.1 m，Te = 1.76 s 试验66：Hs = 0.1 m，Te = 1.80 s 试验67：Hs = 0.1 m，Te = 2.02 s 试验68：Hs = 0.1 m，Te = 2.50 s 试验69：Hs = 0.1 m，Te = 3.23 s 试验70：Hs = 0.1 m，Te = 3.58 s 试验71：Hs = 0.1 m，Te = 4.88 s 试验73：Hs = 0.2 m，Te = 2.30 s 试验74：Hs = 0.2 m，Te = 2.67 s 试验75：Hs = 0.2 m，Te = 3.19 s 试验76：Hs = 0.2 m，Te = 5.02 s
