Data description and turbine wake analysis are presented in the attached manuscript \"Wake measurements from a hydrokinetic river turbine\" by Guerra and Thomson (recently submitted to Renewable Energy).\nThere are three data sets: NoTurbine (prior to deployment), Not_Operational_Turbine (turbine underwater, but not operational), and Operational_Turbine. The data has been quality controlled and organized into a three-dimensional grid using a local coordinate system described in the paper. All data sets are in Matlab format (.mat). \n\nVariables available in the data sets are:\nqx: X coordinate matrix (m)\nqy: Y coordinate matrix (m)\nz : z coordinate vector (m)\nlat : grid cell latitude (degrees)\nlon: grid cell longitude (degrees)\nU : velocity magnitude (m/s)\nUx: x velocity (m/s)\nVy: y velocity (m/s)\nW: vertical velocity (m/s)\nPseudo_beam.b_i: pseudo-along beam velocities (i = 1 to 4) (m/s) (structure with raw data within each grid cell)\nbeam5.b5: 5th-beam velocity (m/s) (structure with raw data within each grid cell)\ntke: turbulent kinetic energy (m2/s2)\nepsilon: TKE dissipation rate (m2/s3)\nReynolds stresses: uu, vv, ww, uw, vw (m2/s2)\n\nVariables from the Not Operational Turbine data set are identified with _T\nVariables from the Operational Turbine data set are identified with _TO", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/248/Guerra_Thomson_Wake2018_submission.pdf", "description": "Research manuscript recently submitted to Renewable Energy Journal.
