Mod-TI Synthetic Inflow Dataset for the G1 Wind Farm Control Benchmark

This repository provides Moderate turbulence intensity (Mod-TI) synthetic atmospheric boundary layer inflow field generated through large-eddy simulations (LES) and used in numerical studies of wind-farm control strategies.

The inflow field was generated using the Simulator fOr Wind Farm Applications (SOWFA) framework. The numerical setup explicitly reproduces the spires elements used in the wind-tunnel facility, allowing the numerical simulations to replicate the atmospheric boundary layer conditions generated in the wind-tunnel experiments.

The simulation reproduces the wind-tunnel inflow used in the experimental campaign of the three-turbine G1 wind-farm benchmark.

Velocity fields were sampled along a vertical plane located 19.1 m downstream of the inlet, corresponding to 10 m upstream of the turntable center in the wind-tunnel setup. This location is therefore very close to the experimental inflow measurement plane.

For each time step:

• the three velocity components (u, v, w) are provided

• values are sampled at the LES mesh nodes

The mesh node coordinates are provided in a separate file.

Temporal resolution and duration are:

The inflow fields can be scaled using the same procedure applied to the experimental inflow measurements, as described in the associated dataset paper.

This inflow have been used in several studies to numerically assess the performance of wind-farm control strategies applied to clusters of G1 wind turbines.
