Flow-induced oscillations of pitching swept wings: Stability boundary, vortex dynamics and force partitioning
Yuanhang Zhu, Kenneth Breuer
We experimentally study the aeroelastic instability boundaries and three-dimensional vortex dynamics of pitching swept wings, with the sweep angle ranging from 0 to 25 degrees. The…
An improved aerodynamic model for quasi-steady simulations of animal flight at moderate Reynolds numbers
Yunxing Su, Xiaozhou Fan, Kyohei Onoue +2
We report on experimental and numerical studies aimed at developing an improved paradigm to model animal flight at moderate Reynolds numbers (). A series of experimen…
Force moment partitioning and scaling analysis of vortices shed by a 2D pitching wing in quiescent fluid
Yuanhang Zhu, Howon Lee, Sushrut Kumar +3
We experimentally study the dynamics and strength of vortices shed from a NACA 0012 wing undergoing sinusoidal pitching in quiescent water. We characterize the temporal evolution o…
Leading edge vortex formation and wake trajectory: Synthesizing measurements, analysis, and machine learning
Howon Lee, Nicholas Simone, Yunxing Su +4
The strength and trajectory of a leading edge vortex (LEV) formed by a pitching-heaving hydrofoil (chord ) is studied. The LEV is identified using the -criterion method, whic…
Nonlinear fluid damping of elastically mounted pitching wings in quiescent water
Yuanhang Zhu, Varghese Mathai, Kenneth Breuer
We experimentally study the nonlinear fluid damping of a rigid but elastically mounted pitching wing in the absence of a freestream flow. The dynamics of the elastic mount are simu…
Effects of confinement on the dynamics and correlation scales in active fluids
Yi Fan, Kun-Ta Wu, Ali Aghvami +2
We study the influence of solid boundaries on dynamics and structure of active fluids as the height of the container, , changes. Along the varying dimension, the geometry system…
