Current Research Potential Collaborations INORE for the Americas

Numerical and experimental analysis of the near wake of a horizontal axis tidal turbine

Andrew Good, Queens University Belfast, agood01@qub.ac.uk Trying to understand factors that influence structure of near wake; specifically the device inflow conditions, the flow field generated by the support structure, and the flow field generated by the turbine rotor Using CFD (ANSYS CFX) and Particle Imaging Velocimetry (Physical modeling) Doing 1:100 scale, then 1:10 scale, then full scale; plan to verify how accurate it is to do scaling modeling

Unsteady hydrodynamic analysis of a horizontal axis marine current turbine with an integral boundary element method

Jo˜ ao Baltazar, Instituto Superior Tecnico, baltazar@marine.ist.utl.pt Aims to predict pressure and cavitation Has to impose wake geometry Uses in-house code, PROPAN Allows for nonuniform incoming flow Axis moves with turbine Uses rigid wake model and wake relaxation model Models viscous effects on blade Future will see an extension to unsteady flow

Numerical modelling of the response of tidal resonance to the presence of a tidal energy barrage

Laura Finlay, The University of Edinburgh, laura.finlay@ed.ac.uk Looking at how barrage would affect resonance and possibly reduce tidal amplitudes Was going to use ROMS but using TELEMAC2D instead due to more European users Domain is Servern Estuary

An experimental survey in the wake of a horizontal axis turbine

Mair´ ead Atcheson, Queen’s University Belfast, matcheson03@qub.ac.uk Turbine array location optimization Quantify wake generation Does tow tests with turbine called Evopod for wake data Wants to find out how far wake extends, and if the structure

• f the Evopod dominates the wake

Using ADV’s to measure turbulence Wants to compare results from ADV and ADCP measurements for understanding turbulence She is interested in learning more about our work in Puget Sound and seeing the data once it is available

Modelling the flow upstream, through, and downstream of a tidal barrage

Penny Jeffcoate, The University of Manchester, penelope.jeffcoate@postgrad.manchester.ac.uk Look at turbulence downstream of barrage Look at flow effects Do CFD (depth-averaged, STAR-CD) then experimentation (placing barrage in flume and use ADV)

Hydrodynamics of a double-pass translating lift device for extracting energy from tidal currents

Peter Johnson, University College London, peterbjohnson@gmail.com Mooring costs are always high for current turbine designs, so want to avoid as much mooring as possible Do a panel type of turbine Using actuator disk model, point vortex, then 3D vortex method

The Characterization and Design of High Solidity Cross-Flow Tidal Turbines

Raul Urbina, The University of Maine, raul.urbina@umit.maine.edu Use free vortex method model Found that need to include dynamic stall and flow curvature in analytic model Interested in collaboration with UW

Development of Fixed Hydrodynamic Lifting Surfaces to Stabilize Tidal Current Energy Generation Devices

Sam Harding, The University of Edinburgh, s.harding@ed.ac.uk Active gravity base for tidal turbine with lifting levers ”Sea snail” design Looking at tidal directionality

Analysis and testing of a hydrokinetic turbine based on

• scillating hydrofoils

Thomas Kinsey, Universit´ e Laval, thkin6@hotmail.com Technology is well-suited to river beds and shallow waters CFD modeling along with prototype Prototype has been tow-tested

Hydrodynamic tool for assessing tidal current turbine arrays

Thomas Roc, University of Plymouth, thomas.roc@plymouth.ac.uk Decision-making tool for turbine arrays Added momentum sink term into ROMS along with turbulence correction term into k − ω closure model Validate by comparing with Myers and Bahaj 2010

Unsteady wake modelling for arrays of tidal current turbines

Tom McCombes, University of Strathclyde, tom@esru.strath.ac.uk Wrote the code in C++ Models turbine, but focus is on wake Using Navier-Stokes in vorticity-velocity form

Turbulence: ADV vs. ADCP

Want to quantify turbulence, specifically wake turbulence, using an ADCP which gets more data in the same amount of time as an ADV Mair´ ead at Queen’s University Belfast

Turbine Modeling

Multiple people modeling turbines – Compare results with Teymour? Provide wake geometry to Jo˜ ao

Kristen Thyng and Chris Bassett INORE Symposium 2010

ROMS Modeling

Tom Roc at University of Plymouth is implementing a turbine model in ROMS We discussed trying his modified code out on my idealized simulations Down the road, try his code out on my realistic model Have been emailing to begin collaboration

Post Doc?

INORE could be a good place to look for a post doc in the next year or two Tom Roc? Turbine Modeler?

People

Already have connections to UW, OSU, U Maine, U Victoria, Stanford, U Delaware, a few more Try to get student connections with MREC in New England, FAU, UBC, Chilean Universities, and others Have connected with Howard Hansen at FAU and Michelle Teng at U Hawaii

Current Research Potential Collaborations INORE for the Americas

Events

Low-key workshop associated with Oceans 2010 conference in Seattle in September Any suggestions for a industry speaker at the event? Possible small workshop also associated with OREG conference in Vancouver in October Would like to build up to a fully-supported/sponsored symposium, very similar to current symposiums

Kristen Thyng and Chris Bassett INORE Symposium 2010

Current Research Potential Collaborations INORE for the Americas

Support

Interested in finding connections to let as many related students know about INORE as possible Need to find good funding sources Establish strong connections with both industry and universities, and ideally NREL/DOE/PNNL/National Labs Eric Stoutenberg at Stanford is taking the lead for INORE for the Americas activities
