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…
Learning Discrepancy Models From Experimental Data
Kadierdan Kaheman, Eurika Kaiser, Benjamin Strom +2
First principles modeling of physical systems has led to significant technological advances across all branches of science. For nonlinear systems, however, small modeling errors ca…
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…
