The software solves the Navier-Stokes flow equations by an averaging procedure known as RANS-modeling. The RANS equations are solved for unsteady, incompressible flow. Equations for the unknown turbulence and turbulent dissipation can be modeled choosing from 3 different models. Turbines are modeled using state of the art methods such as Actuator Disk and Blade Element Momentum theory. Modeling of the atmospheric boundary layer includes both stable, neutral and unstable conditions. FLACS-Wind also handles sloping terrain for simulations onshore and close-to-shore. Upcoming features include a parallelized version and advanced tools for setup of multiple run scenarios.
In addition FLACS-Wind comes with i) a preprossing tool for defining the simulations including boundary conditions, run parameters, terrain import and griding, ii) a runmanager for monitoring the simulations and iii) a postprocessing tool for visualization and analyzing the results, all with user-friendly GUI. The preprossesing tool offers wizards for setting up boundary conditions for a given wind direction and defining a new turbine type including specification of thrust and power curves.
FLACS-Wind builds on the commercial code, FLACS, which has been the leading CFD tool for explosion consequence predictions of petrochemical installations for more than a decade. More than 30 years of dedicated development is behind FLACS.
