Wind Flow Curvature Study
Using a WindSim CFD model, this correction study quickly improves the accuracy of your remote sensing data in complex terrain.
Remote sensing devices use SoDAR or LiDAR to measure wind speed and direction at and above the hub height of today’s taller wind turbines. In areas of complex terrain that have convex flow curvature, a bias can be introduced to remote sensing system measurements. A Wind Flow Curvature Correction Study can be used to convert remote sensing data from your wind campaign into “corrected” winds, using a WindSim Computational Fluid Dynamic (CFD) model.
This service is currently available for Vaisala Triton Wind Profiler data.
The Wind Flow Curvature Correction Study primarily consists of a quantitative examination of the provided Triton Wind Profiler data. A CFD model is applied to the domain where the Triton Wind Profiler is installed and the output is a 3D wind vector grid with 5m horizontal resolution and 20m vertical resolution. Vaisala creates an adjustment factor to convert Triton Wind Profiler measured winds into “correct” winds using a two-dimensional look-up table by wind direction and height. The client is provided the corrected dataset, but the original data set remains unchanged for comparison purposes.
For an additional fee, CFD corrections can also be applied to the Triton Wind Profiler "correct" winds to adjust for the difference in wind behavior from the Triton Wind Profiler to the nearby met tower.
