Simulations of Intracycle Angular Velocity Control for a Cross-Flow Turbine
Mukul Dave, Benjamin Strom, Abigale Snortland +3
Straight-bladed cross-flow turbines are computationally explored for harvesting energy in wind and water currents. One challenge for cross-flow turbines is the transient occurrence…
Geometric and Control Optimization of a Two Cross-Flow Turbine Array
Isabel Scherl, Benjamin Strom, Steven L. 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…
Phase-consistent dynamic mode decomposition from multiple overlapping spatial domains
Aditya G. Nair, Benjamin Strom, Bingni W. Brunton +1
Dynamic mode decomposition (DMD) provides a principled approach to extract physically interpretable spatial modes from time-resolved flow field data, along with a linear model for…
Robust Principal Component Analysis for Modal Decomposition of Corrupt Fluid Flows
Isabel Scherl, Benjamin Strom, Jessica K. Shang +3
Modal analysis techniques are used to identify patterns and develop reduced-order models in a variety of fluid applications. However, experimentally acquired flow fields may be cor…
Intracycle Angular Velocity Control of Cross-Flow Turbines
Benjamin Strom, Steven L. Brunton, Brian Polagye
Cross-flow turbines, also known as vertical-axis turbines, have numerous features that make them attractive for wind and marine renewable energy. To maximize power output, the turb…
