Work Package 1 – MIRACLES: LES simulation code for turbine blade operation

The objective of Work Package 1 (WP1) was to develop and apply a computational fluid dynamics (CFD) model for simulating tidal turbine blade cavitation in order to explore various passive and active cavitation control strategies and then consider implementing them on a full model of a multi-bladed tidal turbine.

Public deliverables:

Work Package 2 – Active Flow Control strategies and novel test-rigs for tidal turbine composite blades

This work package acted as support for design optimisations completed in WP 4-5 for the Magellan device. To facilitate improved design numerical models were validated by model testing, active and passive flow control was developed to improve efficiency and the effect of fouling and cavitation erosion. Test rigs to accomplish the above were developed and increased capability in numerical models was an effect.

Public deliverables:

Work Package 3 – Nano-reinforced composites, antifouling coatings and antifouling biomimetic surfaces

WP3 dealt with the integration of new materials for the blades. These materials could be at nanometric scale inside the blade to increase the mechanical properties or enhanced coatings with increased barrier wear, impact and anti-fouling properties and bio-mimetic surfaces to protect blades against ageing, wear and biological growth effects.

Public deliverables:

Work Package 4 – Testing Campaign for Behavioural Models Development

WP4 was devoted to testing, characterising and validating results coming from WP2 and WP3. The best performing materials developed in WP3 were tested and characterised at lab and field scale, while accuracy and repeatability of test rigs and testing procedures developed in WP2 were validated. The results obtained in WP4 were the basis for the design of innovative and enhanced models, testing and procedures in WP5.

Work Package 5 – Innovative and enhanced models, testing and design procedures

In WP5 numerical methodologies for the design of new generation tidal blades were developed. These numerical methodologies include ageing, fouling and wear modeling, material design, and damage tolerance calculation. The WP resulted not only in an enhanced tidal blade prototype fulfilling the project requirements but also in a methodology for the design of future tidal blades.

Public deliverables:

Work Package 6 – Cross-cutting activities

In WP6 NEMMO’s consortium analysed the environmental impacts of the project outcomes along its life cycle based on two different scenarios: a 34MW tidal farm, and a 100MW one. Firstly, a cradle-to-grave approach analysis from manufacturing to final decommissioning was performed. Secondly, project outcomes were validated through a techno-economic assessment to estimate LCOE achievements by 2025 and 2030. And finally, a socio-economic assessment with relevant actors and social systems was performed, so social impacts and barriers were identified.

Public deliverables:

Work Package 7 – Exploitation, Dissemination and Communication

WP7 was split into two parts. Firstly, communications and dissemination activities were undertaken to maximise project visibility and recognition, and to ensure that results are shared as widely as possible with target audiences. The second part – exploitation – focused on protecting the results and knowledge generated by the project, and further commercialising the project innovations.

Public deliverables:

Work Package 8 – Project Management

And finally, WP8 made sure that both the general project objectives and the individual work package objectives were met, while controlling project costs, managing and monitoring risks, and legal and contractual aspects of the project. Last but not least, internal and external communication were both managed to ensure optimal information flow among all key stakeholders.
