Experimental identification of blade-level forces, torque, and pitching moment for cross-flow turbines
Abigale Snortland, Katherine Van Ness, Jennifer A. Franck +3
Cross-flow turbine power is a net sum of power generation from rotating blades and power loss from rotating support structures. While the aggregate forces and torques at the turbin…
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…
Near Wake Dynamics of a Cross-Flow Turbine Array
Isabel Scherl, Abigale Snortland, Steven Brunton +1
Cross-flow turbines, also known as vertical-axis turbines, convert the kinetic energy in moving fluid to mechanical energy using blades that rotate about an axis perpendicular to t…
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…
