Unsteadiness in turbulent separated flow over a three-dimensional Gaussian bump
Kevin H. Manohar, Hariprasad Annamalai, Owen Williams +2
The unsteady separated flow over the three-dimensional Boeing Gaussian Bump is investigated at a Reynolds number based on bump height using unsteady wall-pr…
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…
Compressible Boundary Layer Velocity Transformation Based on a Generalized Form of the Total Stress
Han Lee, Pino Martin, Owen Williams
The effects of density and viscosity fluctuations on the total stress balance are identified and used to create a new mean velocity transformation for compressible boundary layers.…
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…
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…
