CFD MODELING OF FOREST CANOPY FLOWS: INPUT PARAMETERS, CALIBRATION AND VALIDATION
Wind flow simulations on forested zone have been performed with Computational Fluid Dynamics (CFD) software Meteodyn WT, which allows introducing a custom forest canopy model.
The influence of parameter changes on results is investigated. The calibration of model parameters is done by minimizing the error between the CFD results and the vertical wind profiles given by the European standard Eurocode 1 (EC1), applied to standard terrains for high roughness cases. The calibrated model shows good coherence with EC1.
To check the validity of the forest modeling in the real case, CFD simulation has been performed on a site with heterogeneous forest covering. The computed wind characteristics are then compared to met mast measurement. The comparison shows good agreement on wind shear and turbulence intensity between the simulation results and the measured data.
