Energy Generation Wind Turbines Fluidyn PANEOLE


fluidyn-PANEOLE is the module of the software platform fluidyn-PANACHE dedicated to the generation of wind turbine potential atlas.


It had been developed with active support from ADEME, the French Ministry of Environment Agency to answer the requirements and specifications of the upcoming wind energy sector. It was developed to derive from mesoscale data, a microscale energy potential prediction of a site for wind turbines.


fluidyn-PANEOLE offers wind turbines developers a reliable and high precision tool capable of generating a wind field atlas for the wind turbines farm siting while also integrating wake effect. It generates a wind field atlas for efficient positioning of turbines at a regional or local scale e.g. in a domain of 300 x 300 Km. This includes local boundary layer effects such as flow detachment, venturi effect between hills or large buildings, surface roughness generated turbulence or sea breeze.


Energy Generation Wind Turbines Fluidyn PANEOLE


fluidyn-PANEOLE has an integrated GIS generation facility. It can also import files from other GIS software. It has a post-processor to prepare wind energy prediction for each turbine for next few days. Its wind flow simulator is a fully turbulent flow solver. The solver can simulate the wind field on a highly complex terrain with locally refined flow around wind mills. They are all integrated in one single user interface.


Wind field is modeled by solving the 3D equations of fluid dynamics, the Navier-Stokes equations. It is initialized by interpolating weather data by Lagrangian multipliers. It ensures :


  • conservation of mass and momentum by using unstructured Finite Volume meshing
  • corresponds exactly to the weather station measurements
  • takes into account the influence of topography

The CFD solution considers transient and stationary weather parameters (sun, sea breeze, short-term wind fluctuations). A specific turbulence model (the two-equation model k-e) is used to account for obstacles, topography, and temperature variation.


The computational domain can have horizontal dimensions from a few hundred meters to several hundred kilometers, and can be several hundred meters high. Mesh around the wind turbines may have a refinement of the order of a meter.


Files import and export with other software formats (GIS systems such as AUTOCAD, MAP INFO, etc. or meteorological models such as MM5) allow an easy result analysis.


While the interface is user-friendly, the numerical model of terrain is generated easily from maps by the user with automatic generation of mesh. The numerical parameters of the solver (boundary conditions, turbulence model) are chosen by default according to atmospheric conditions
