Task 1.1 (DTU) - Multi-Scale modelling of manufacturing induced defects in OWT blades
Task 1.2 (LIV) - CFD investigation of the near-blade 3D flow for a complete OWT configuration

One of the many challenges the Wind Energy Industry has to face, concerns the polymer fiber composite material and structures utilized in the OWT blades. WP1/Task1.1 will cover the exploration of innovative low cost carbon fiber reinforced composites introduced in addition to glass fiber reinforced composites, along with other perspective material solutions, in order to reduce the weight without scarifying the strength.

The trend towards large diameter offshore rotors makes efficient CFD methods for the analysis of OWT very attractive. The majority of the methods employed nowadays for OWT power’s calculation are based on Blade Element Momentum. The progress beyond state of the art to be pursued by the WP1/Task1.2 will be development and application of algorithms for the effective aeroelastic analysis of very-large scale OWTs.
