  High-fidelity analysis of fluid physics and structural response using Large-Eddy Simulations and FAST.

by Matt Churchfield and Sang Lee

SOWFA (Simulator for Offshore Wind Farm Applications) is a computational fluid dynamics solver based on OpenFOAM coupled with FAST which allows users to investigate wind turbine performance under variable atmospheric conditions.

The package includes:
  • Atmospheric boundary layer (ABL) solver
  • Wind farm solver with standard actuator line
  • Large eddy simulation (no temperature equation) with FAST actuator line
  • Wind farm solver FAST actuator line (beta version)
  • Specific boundary conditions class
  • Standard actuator line class
  • FAST actuator line class
  • Utility to set ABL IC's and BC's
  • Utility to change sampled boundary files to input files for wind farm upstream BC's
Sample Cases:
  • Precursor simulation of atmospheric boundary layer
  • Wind farm simulation of 48 NREL 5MW turbines using standard actuator line
  • Four NREL 5MW reference wind turbine using FAST actuator line
  • ABL simulation with 2 NREL 5MW turbines using FAST actuator line (beta version)
