Services to Wind Turbine Manufacturers and OEMs
Servo-hydro-aero-elastic analysis of Wind Turbine systems
We employ in-house tools for a full servo-hydro-aero-elastic analysis of wind turbine systems including:
- Loads assessment of onshore and offshore (bottom-fixed and floating) WTGS, according to IEC standard
- Aeroelastic design and stability analysis regarding stall-induced vibrations (SIV). Identification of low/negatively damped modes under normal operation, parked/idling conditions and during assembly.
- Novel vortex-induced vibrations (VIV) aeroelastic analysis of the entire WT configuration.
Wind Turbine conceptual design
Airfoil and rotor aerodynamic design
These services are mostly addressing large multi-megawatt onshore and offshore designs of non-conventional specific power characteristics:
Airfoil and rotor aerodynamic analysis
All aerodynamic simulations are carried out with in-house tools in the context of CFD (3D, 2 1⁄2 D or 2D) and Vortex Methods. Our current capabilities include a) Steady and unsteady flow simulations, b) Incompressible and Compressible flow solvers, c) Extensive use of parallel processing (Open MP and MPI) and d) Turbulence and transition modeling.
These services are mostly addressing large multi-megawatt onshore and offshore designs of non-conventional specific power characteristics:
- Optimum design of dedicated high and low lift airfoil families suitable for given Reynolds and Mach number regimes
- Shape optimization of wind turbine blades for lowering the cost of energy
