Wind Tunnel Double-Wake Dataset with Multi-Probe Three-Component Velocity Measurements (NetCDF Collection)

This repository provides an open experimental dataset obtained from a wind tunnel campaign designed to characterise double-wake conditions in a scaled multi-turbine setup. The dataset focuses on flow measurements in the wake generated by the second turbine (WT2) and contains approximately 70 tests, each stored as an individual NetCDF4 file. Contents Each NetCDF file includes: Wind tunnel reference signals (/WindTunnelData): reference velocity, turntable angle, air density Multi-probe flow measurements (/FlowData): three-component velocity time series (ux, uy, uz) probe positions (x, y, z) probe acquisition start time (InitTime) Wind turbine signals and loads (/WTsData, WT1–WT2): operational signals (rotor speed, yaw, yaw demand, azimuth) pitch signals (measured and demanded) electrical power signals tower loads (fore-aft / side-side) hub loads (yawing, nodding, torque) Multiple acquisition rates are present (high-frequency turbine loads and azimuth, slower wind-tunnel and turbine signals, and probe time series), enabling both wake-flow analysis and turbine response investigations. Applications The dataset supports: characterisation of interacting wakes (double-wake scenarios) validation of wake models (engineering and reduced-order) benchmarking of high-fidelity simulations (LES / actuator-line) control-oriented analyses and system identification under wake interaction conditions combined flow–loads studies in wake-affected inflow
