| Zusammenfassung |
| Wind speed measurements over the ocean on ships or buoys are affected
by flow distortion from the platform and by the anemometer itself.
This can lead to errors in direct measurements and the derived
parametrisations. Here we computational fluid dynamics (CFD) to
simulate the errors in wind speed measurements caused by flow
distortion on the RV Celtic Explorer. Numerical measurements were
obtained from the finite-volume CFD code OpenFOAM, which was used to
simulate the velocity fields. This was done over a range of
orientations in the test domain from −60 to +60°
in increments of 10°. The simulation was also set up for a
range of velocities, ranging from 5 to 25 m s−1 in
increments of 0.5 m s−1. The numerical analysis showed close
agreement to experimental measurements. |
