Library-learning-assisted robust principal component analysis for denoising severely corrupted flow fields
Pablo Koop, Isabel Scherl, Kai Fukami
Large-amplitude entrywise corruption can distort flow-field data and contaminate extracted modes. Robust principal component analysis (RPCA) separates low-rank flow content from a…
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…
Reduced-order modeling and classification of hydrodynamic pattern formation in gravure printing
Pauline Rothmann-Brumm, Steven L. Brunton, Isabel Scherl
Hydrodynamic pattern formation phenomena in printing and coating processes are still not fully understood. However, fundamental understanding is essential to achieve high-quality p…
Data-Driven Modeling for On-Demand Flow Prescription in Fan-Array Wind Tunnels
Alejandro A. Stefan-Zavala, Isabel Scherl, Ioannis Mandralis +2
Fan-array wind tunnels are an emerging technology to design bespoke wind fields through grids of individually controllable fans. This design is especially suited for the turbulent,…
Wave and turbulence separation using dynamic mode decomposition
Julio Chávez-Dorado, Isabel Scherl, Michelle DiBenedetto
Separating the effects of waves and turbulence in oceanographic time series is an ongoing challenge because surface wave motion and turbulence fluctuations can occur at overlapping…
Bio-Inspired Compensatory Strategies for Damage to Flapping Robotic Propulsors
Meredith L. Hooper, Isabel Scherl, Morteza Gharib
To maintain full autonomy, autonomous robotic systems must have the ability to self-repair. Self-repairing via compensatory mechanisms appears in nature: for example, some fish can…
An experimental evaluation of the interplay between geometry and scale on cross-flow turbine performance
Aidan Hunt, Benjamin Strom, Gregory Talpey +5
Cross-flow turbines harness kinetic energy in wind or moving water. Due to their unsteady fluid dynamics, it can be difficult to predict the interplay between aspects of rotor geom…
Cycle-to-cycle variations in cross-flow turbine performance and flow fields
Abigale Snortland, Isabel Scherl, Brian Polagye +1
Cross-flow turbine performance and flow fields exhibit cycle-to-cycle variations, though this is often implicitly neglected through time- and phase-averaging. This variability coul…
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…
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…
