Prediction of dynamic loads and induced vibrations in stall

Objective



Objectives

The objectives of this project are to provide improved design and analysis tools for the stalled horizontal axis wind turbine (HAWT) rotor. The work supports the design of large-scale stall-regulated rotors, bringing together and exploiting the knowledge gained from research carried out under JOULE I and JOULE II. The overall objectives of the project are - Improvement of the prediction capabilities with respect to dynamic loads in stall and stall induced vibrations and
- Establishment of guidelines aiming at achieving safety margins against stall induced vibrations.


Technical Approach

The objectives of the project will be achieved by the following main work packages:
- Analysis and synthesis of existing field rotor measurements. Particularly, stall hysteresis on both CN and CT curves will be investigated.
- Further development (update) of the engineering models for stall hysteresis and 3-D effects based on existing data (field rotor data and wind tunnel data). In particular, the unsteady aerodynamics from the variation of the relative velocity and the blade edgewise vibration will be considered and how this can be taken into account in the stall hysteresis models.
- Implement the engineering models in aeroelastic models and carry out calculations on one turbine, e.g. a 500 kW with 40 m rotor diameter. - Compare with measurements} and make investigations of influence from parameter variation in the engineering models.
- Investigate the influence on edgewise and pitching vibration of the blade from a variation of blade and turbine parameters (blade planform, airfoil characteristics, rotational speed, blade modal form, natural frequencies).
- Derive guidelines for blade design in order to avoid stall induced vibrations.


Expected Achievements and Exploitation

The outcome of the project is improved and validated aeroelastic models with updated submodels for stall hysteresis and 3-D flow effects. In particular improvement of prediction of edgewise stall induced vibrations is considered. Such improved prediction capabilities together with derived design guidelines for safety margins against stall induced vibrations are made available for the industry.
