113 files -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: 2. Methods for processing the data: 3. Instrument- or software-specific information needed to interpret the data: Use and analysis of output requires MATLAB. 4. Standards and calibration information, if appropriate: N/A. 5. Environmental/experimental conditions: 6. Describe any quality-assurance procedures performed on the data: 7. People involved with sample collection, processing, analysis and/or submission: ------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: Dual Turbine Experiments.zip ------------------------------------------------- Data are organized by measurement type. 3 Folders: ------ Topography - Laser Scans Final Topography: ------ This folder contains the Final Topography laser scan for the baseline case (DEM_Baseline_Tecplot.dat), a single centered turbine case (DEM_SingleTurb_Tecplot.dat) and the dual-turbines asymmetric case (DEM_Asym_Tecplot.dat). At the end of each experiment, the channel was carefully drained and a laser scan of the final topography was acquired. These .dat files represent a X-Y-Z matrix and the coordinates are all normalized by the turbine rotor diameter (d_T=0.15m). x=0 and y=0 correspond to the turbine x-location and the channel centerline respectively. The bed elevations (z coordinate) for all the scans are detrended subtracting the baseline averaged bed (see referenced paper for details) which thus represents z=0. The baseline and the asymmetric final topography data were used to reproduce Figure 3 in the referenced paper using Tecplot. ------ Topography - Sonar Continuous Scans ------ Bed elevation and water surface longitudinal continuous scans. Bed elevation was measured using a submerged sonar while the water surface was measured using an ultrasonic Massa instrument (see experimental setup in the referenced article). The folder is sub-divided into the three cases presented in the paper: Baseline, Experiment 1 (with turbines asymmetrically installed on the left hand side of the flume) and Experiment 2 (with turbines asymmetrically installed on the right hand side of the flume). Repeated scans were acquired along three longitudinal lines along the channel: P1 is the right line, P2 is the center line and P3 is the left line, all with respect to the water flow direction (see schematic in Figure 1 in the referenced article). Each measurement matrix ends with the line-specific indicator (_P*). Each case includes the same data set structure: SonarScan_BED_P*: bed elevation x-t matrices from the sonar instrument; columns refer to consecutive passes (t) while rows correspond to the longitudinal (x) coordinates. These data are in mm and in the flume coordinates system. The detrending procedure (subtract the scans with an average fit and make bed elevation fluctuate around 0) is explained in the Experimental Setup of the referenced paper; SonarScan_WATER_P*: water surface x-t matrices from the Massa instrument; columns refer to consecutive passes (t) while rows correspond to the longitudinal (x) coordinates. These data are in mm and in the flume coordinates system; Pass_temporal_freq: scan average temporal resolution (time between passes, in seconds); Xbed: Sonar (bed elevation) scan longitudinal coordinates vector (mm); Xwater: Massa (water surface elevation) scan longitudinal coordinates vector (mm). These data were used to reproduce Figure 2, 4, 5 and 6 of the referenced paper. —- Baseline Notes: — This good DataSet extrapolated is from the 10th to the 21th (end) hr. - SonarScan_BED_P* refers to topography x-t matrices - SonarScan_WATER_P* refers to water surface x-t matrices - Pass_temporal_freq: scan average temporal resolution - Xbed: Sonar (bed elevation) scan longitudinal coordinates - Xwater: Massa (water surface elevation) scan londitudinal coordinates Scan lines and names: P1 -> right P2 -> center P3 -> left Lines are referenced with respect to the flow direction point of view. —- Experiment 1 LHS Notes —- This data set represents 7 hrs after 15 h and 40 min of run.

It was taken from hr 12 to hr 19(end) of scan2. (scan 2 started after 4.5hrs of run). Total experiment time: ~ 23.5 hrs. - SonarScan_BED_P* refers to topography x-t matrices - SonarScan_WATER_P* refers to water surface x-t matrices - Pass_temporal_freq: scan average temporal resolution - Xbed: Sonar (bed elevation) scan longitudinal coordinates - Xwater: Massa (water surface elevation) scan londitudinal coordinates Scan lines and names: P1 -> right P2 -> center P3 -> left Lines are referenced with respect to the flow direction point of view. —— ------ Velocity - Spanwise Profiles ------ Velocity spanwise profiles acquired using the Moving-ADV technique, as described in the Experimental Setup of the referenced paper. All_Travere_TecFile.dat: includes all the processed ADV data, organized as follow: COLUMNS : X, Y, Z, X_rel/dt, Y_rel/dt (this is corrected in the code below), Z_rel/dt, U, V, W, u_rms loc, v_rms loc, w_rms loc, u_rms_gen, v_rms_gen, w_rms_gen; ROWS: each spanwise profile is one above the other. Thus there are stacks of 741 data. Load_AllTraverse_datfile_and_manage.m: is a Matlab code that loads the .dat file above, reorganizes the data in the individual spanwise profile and plots them. This was used to reproduce Figure 7 in the referenced paper. ------------------------------------------------ DATA-SPECIFIC INFORMATION FOR: Vane-like Array Experiments.zip ------------------------------------------------ Data are organized by measurement type. Folders: ------ Topography - Laser Scans Final Topography ------ Tis folder contains the Final Topography laser scan for the four cases of the Vane Experiments presented. At the end of each case, the channel was carefully drained and a final topography scan was acquired. In particular, data from Experiment 1 and Experiment 3 were used to reproduce Figure 8a and 8b. o TopoDetrended: final topography already detrended subtracting a fitted plane (mm); o SICK_Variables: spatial coordinates (x,y) and resolution (dx,dy) of the scan. This Matlab workspace includes also the non-detrended topography scan (DEM_new), all in mm. o Topo_detrended_Clean: it coincides with TopoDetrended but the measurements at the turbine locations (bad data) are removed and interpolated using surrounding topography values (for plotting purposes), all in mm. ------ Topography - Sonar Continuous Scans ------ Bed elevation and water surface longitudinal continuous scans. Bed elevation was measured using a submerged sonar while the water surface was measured using an ultrasonic Massa instrument (see experimental setup in the referenced article). The folder is sub-divided into the four cases presented in the paper: Experiment 1, Experiment 2, Experiment 3 and Experiment 4. Repeated scans were acquired along two longitudinal lines along the channel: P1 over the side where the Vane was installed, while P2 is the Unobstructed Side (see schematic in Figure 1b in the referenced article). Each measurement matrix ends with the line-specific indicator (_P*). Each case includes the same data set structure: o SonarScan_BED_P*: bed elevation x-t matrices from the sonar instrument; columns refer to consecutive passes (t) while rows correspond to the longitudinal (x) coordinates. These data are in mm and in the flume coordinates system. The detrending procedure (subtract the scans with an average fit and make bed elevation fluctuate around 0) is explained in the Experimental Setup of the referenced paper; o SonarScan_WATER_P*: water surface x-t matrices from the Massa instrument; columns refer to consecutive passes (t) while rows correspond to the longitudinal (x) coordinates. These data are in mm and in the flume coordinates system; o Pass_temporal_freq: scan average temporal resolution (time between passes, in seconds); o Xbed: Sonar (bed elevation) scan longitudinal coordinates vector (mm); o Xwater: Massa (water surface elevation) scan longitudinal coordinates vector (mm). These data were used to reproduce Figure 8c, 8b, 9 and 10 of the referenced paper. ------ Velocity - Spanwise Profiles ------ Single inflow measurement (INFLOW) in the center of the channel upstream of the array, and spanwise velocity profile (11 points) measured downstream of the Vane array at hub height during Experiment 1, as presented in Figure 11a in the referenced paper. Specifically: • INFLOW : X = 34 m, Y = 1375 m (center channel), 200 Hz, 15 min; • PT 1 : X = 6 dt (downstream of last turbine) m, Y = 2525, 200 Hz, 10 min; • PT 2 : X = 6 dt (downstream of last turbine) m, Y = 2300, 200 Hz, 10 min; • PT 3 : X = 6 dt (downstream of last turbine) m, Y = 2075, 200 Hz, 10 min; • PT 4 : X = 6 dt (downstream of last turbine) m, Y = 1850, 200 Hz, 10 min; • PT 5 : X = 6 dt (downstream of last turbine) m, Y = 1625, 200 Hz, 10 min; • PT 6 : X = 6 dt (downstream of last turbine) m, Y = 1400, 200 Hz, 10 min; • PT 7 : X = 6 dt (downstream of last turbine) m, Y = 1175, 200 Hz, 10 min; • PT 8 : X = 6 dt (downstream of last turbine) m, Y = 950, 200 Hz, 10 min; • PT 9 : X = 6 dt (downstream of last turbine) m, Y = 725, 200 Hz, 10 min; • PT 10 : X = 6 dt (downstream of last turbine) m, Y = 500, 200 Hz, 10 min; • PT 11 : X = 6 dt (downstream of last turbine) m, Y = 225, 200 Hz, 10 min; • Y = 0 corresponds to the channel left wall (with respect to the flow direction). o The matfiles (MHK_Vane_Run4_SpanProf_PT_*) are the UVW timeseries for each point. The variable has 3 cloumns: U, V, W (m/s). o Ycoord is a vector with the y-coordinates of the points (mm). o ADVdata_summary_FilteredData.xlsx includes the summary of all the averaged statistics for each point. ------ Voltage - Exp 1 ------ Voltage measurements time series for each individual turbine recorded during Experiment 1. The averaged values are plotted in Figure 11b of the referenced paper. The voltage recording was limited to a total duration of 10 minutes due to memory restrictions; the total voltage time series is the combination of all the consecutive 10-min interval recordings. The short time between consecutive recordings was filled with NaNs to have a continuous time series. Each matrix has 3 columns: • Column 1: recording number; • Column 2: voltage signal (volts); • Column 3: time vector (seconds). The average general trend is calculated between min 150 and 300, where the signal looked "less disturbed"
