Inverse design of wind turbine blades for extreme weather applications

Description of the research topic

“The project aims to determine the shape of wind turbine blades considering the prevailing icing conditions of the wind farm, and to evaluate the performance of the wind turbine under such conditions. Ice accretion on rotor blades considerably worsens the aerodynamic performance of wind turbine systems by reducing lift generation and increasing drag, which leads to power loss up to 30% at sites with particularly high risk of icing. Furthermore, ice accumulation also affects safety and lifetime of the wind turbines. Therefore, effort should be made to reduce the effects of ice accretion, which enables wind turbines to operate under a wider range of ambient conditions.
An inverse design methodology is applied to find a blade shape if the required pressure or velocity distribution around the blade is known. If meteorological conditions justify, the velocity distribution should be modified by the application of a correction factor so that the aerodynamic performance degradation becomes less severe due to icing. The blade shape is determined by several geometrical parameters (e.g. camber line, thickness), which affect the aerodynamic performance of the blade. Further series of parameters that influence the aerodynamics of the blade describe the ambient conditions including flow conditions and icing conditions. The correction factor should consider these parameters and phenomena. Involving such a correction factor in the design process will enable the wind turbine to operate under some icing conditions satisfactorily.”
