The Structural Design of Wave Energy Devices (SDWED) project, led by Aalborg University, has had an amazing output of free software including advanced hydrodynamic models, wave to wire models, and a spectral fatigue model:
Also, at the bottom of that page is a list many other free software products.
“The Structural Design of Wave Energy Devices project (SDWED) 2010-2014 is an international research alliance supported by the Danish Council for Strategic Research. The project is a five-year endeavour to harness the energy potential in wave energy at competitive costs.” (www.sdwed.civil.aau.dk/)
MoorDyn is a lumped-mass mooring line model designed for easy coupling with other software (i.e. floating platform models). It supports arbitrary line interconnections, clump weights and floats, and different line properties. The model accounts for internal axial stiffness and damping forces, weight and buoyancy forces, hydrodynamic forces from Morison’s equation, and vertical spring-damper forces from contact with the seabed.
The original version is written in C++ and has been successfully coupled with FAST v7 and other tools/models in Matlab and Simulink. A separate Fortran-based version has recently been incorporated into FAST v8 (nwtc.nrel.gov/FAST8). More information and downloads can be found at www.matt-hall.ca/software/moordyn.
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
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 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!
