DTOcean

dtocean

DTOcean, which stands for Optimal Design Tools for Ocean Energy Arrays, aims at at accelerating the industrial development of ocean energy power generation knowledge, and providing design tools for deploying the first generation of wave and tidal energy converter arrays. It gathers 18 partners from 11 countries (Ireland, Spain, United Kingdom, Germany, Portugal, France, Norway, Denmark, Sweden, Belgium and United States of America) under the coordination of the University of Edinburgh.

DTOcean work planning has been implemented as five content-orientated Work Packages (Hydrodynamics, Electrical Sub-systems, Moorings & Foundations, Installation and Operations & Maintenance) guided by two defining work packages (Scenarios and Management & Coordination) which set the underpinning scope in relation to a range of array sizes and hydrodynamic layouts. The outputs, feedbacks and interactions within these culminate in the Integration Work Package where the design tools are actually developed.

The newly released, open-source, integrated DTOcean v1.0 software package can be downloaded here.

UNH-RVAT baseline performance and near-wake measurements

The Reference Vertical Axis Turbine (RVAT) experiments were tidal turbine tests conducted “with a 1 m diameter, 1 m tall three-bladed vertical axis turbine in a towing tank” by Peter Bachant and Martin Wosnik of the Center for Ocean Renewable Energy at the University of New Hampshire. For more info, see their paper.

They have released a repository on GitHub, which contains the processing and plotting code, as well as the derived data set from the UNH-RVAT tow tank measurements performed in Spring 2013: github.com/UNH-CORE/RVAT-baseline

UNH-RVAT Reynolds number dependence experiment

Researchers, Peter Bachant and Martin Wosnik,  of the Center for Ocean Renewable Energy at the University of New Hampshire  “investigated—experimentally and numerically—the effects of Reynolds number on the performance and near-wake characteristics of a 3-bladed cross-flow turbine” For more info, see their METS paper.

Their are releasing the processing and plotting code, as well as the derived dataset from the UNH-RVAT Reynolds for free on GitHub: github.com/UNH-CORE/RVAT-Re-dep

 

turbinesFOAM

turbinesFoam is a library for simulating wind and marine hydrokinetic turbines in OpenFOAM (2.3.x). Some components for solvers and turbine models have been taken from NREL’s SOWFA and Offwind.

Get it on GitHub: github.com/turbinesFoam/turbinesFoam

This library is in heavy development and is not yet fully functional, but pull requests are encouraged!
