Key R&D Institutions and Relevant R&D Projects:


The New Zealand group led by Dr Ross Vennell has made significant advances in quantifying theoretical impacts of large turbine arrays.

This is enabling ideas around tuning and temporal sequencing of tuning to maximise energy extraction for minimum flow disturbance.
