Webinar replay: Explore the Latest Features of Meteodyn WT 1.8

This webinar introduces the new features of Meteodyn WT in Meteodyn Universe 1.8, with a special focus on the new Mesoscale-Microscale Coupling functionality. Two validation cases of the meso-micro coupling methodology are also presented. We also unveil multiple enhancements, including the ability to launch CFDs for multiple directions and stabilities simultaneously, import stability information from a WRF file, utilize the Molas B300 lidar correction
Poster: Meso-micro scale coupling method for Wind Resource Assessment in large coastal area in India

Discover a new validation case of our meso-micro coupling method, which helps to more accurately assess the wind resource of large wind farms in complex terrain. This scientific poster, authored by Ru Li, Senior Research Engineer at Meteodyn and Eric Tromeur, Director of Research, Innovation, Service & Expertise at Meteodyn, was published for the WindEurope Technology Workshop 2022. Our wind resource assessment modeling for the large wind farm focuses on the meso-micro coupling method. The...
White paper - Atmospheric boundary layer modellisation

From the general characteristics of the atmospheric boundary layer to the impact of thermal effects and stability on turbulence, passing through the Monin-Obukhov's similarity theory, this white paper covers all the knowledge needed for the atmospheric boundary layer modeling. It details the numerical models available for its computation, focusing on the RANS model (k-ε, k-ω, k-L), more suitable for industrial use or for complex site configurations.
Modelling wind flow in forested area: a parametric study

This paper presents an analysis of CFD modelling, using a k-L turbulence model designed for forested areas. Meteodyn and Iberdrola Renovables have undertaken a systematic analysis of measurements data obtained in numerous sites, compared with Computation Fluid Dynamic approach. The analysis has consisted in highlighting the influence of several parameters on the shear defined as the vertical gradient of wind speed and the turbulence intensity at the wind turbine hub height. The influence is...
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...
A Turbulence Model for the Stable Boundary Layer with Application to CFD in Wind Resource Assessment

In wind resource assessment, the impact of the atmospheric thermal stability attracts more and more attention. The first reason is the increase of wind turbines height. The second reason is that the practice of WRA engineering is evolving towards a regular use of time series extrapolations (measurements or mesoscale data) or at least more detailed statistical analysis. Using time series instead of global statistics leads...
