Optimizing the Interplay Between the Chord-to-Radius Ratio, Camber and Pitch of Cross-Flow Turbine Blades
Ari Athair, Aidan Hunt, Han-Wen Chi +1
This study examines the combined impact of the chord-to-radius ratio (c/R), blade camber, and preset pitch on cross-flow turbine performance. While prior research has examined indi…
Experimental validation of a linear momentum and bluff-body model for high-blockage cross-flow turbine arrays
Aidan Hunt, Ari Athair, Owen Williams +1
In a confined flow, the performance of a turbine and its near-wake fluid dynamics depend on the blockage ratio, defined as the ratio of the turbine projected area to the channel cr…
Experimental evaluation of advanced control strategies for high-blockage cross-flow turbine arrays
Aidan Hunt, Gregory Talpey, Brian Polagye
In river or tidal channels, cross-flow turbines can achieve higher blockage ratios than other turbine variants, and are therefore able to achieve higher efficiencies. Here, we expe…
Performance characteristics and bluff-body modeling of high-blockage cross-flow turbine arrays with varying rotor geometry
Aidan Hunt, Gregory Talpey, Gemma Calandra +1
While confinement is understood to increase the power and thrust coefficients of cross-flow turbines, how the optimal rotor geometry changes with the blockage ratio -- defined as t…
