ORPC RivGen Hydrokinetic Turbine Wake Characterization

Abstract
Field measurements of mean flow and turbulence parameters at the Kvichak river prior to and after the deployment of ORPC's RivGen hydrokinetic turbine. 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).
There 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).

Variables available in the data sets are:
qx: X coordinate matrix (m)
qy: Y coordinate matrix (m)
z : z coordinate vector (m)
lat : grid cell latitude (degrees)
lon: grid cell longitude (degrees)
U : velocity magnitude (m/s)
Ux: x velocity (m/s)
Vy: y velocity (m/s)
W: vertical velocity (m/s)
Pseudo_beam.b_i: pseudo-along beam velocities (i = 1 to 4) (m/s) (structure with raw data within each grid cell)
beam5.b5: 5th-beam velocity (m/s) (structure with raw data within each grid cell)
tke: turbulent kinetic energy (m2/s2)
epsilon: TKE dissipation rate (m2/s3)
Reynolds stresses: uu, vv, ww, uw, vw (m2/s2)

Variables from the Not Operational Turbine data set are identified with _T
Variables from the Operational Turbine data set are identified with _TO
