Learning Unknown Constraints without Unsafe Data via Optimality and Counterfactual Regularization
Zhouyu Zhang, Chih-Yuan Chiu, Glen Chou
Learning from demonstrations (LfD) provides a framework for inferring unknown constraints from locally optimal, constraint-satisfying expert behavior. Existing approaches largely f…
Phase-based analysis and control of supersonic turbulent cavity flows
Vedasri Godavarthi, Yoji Kawamura, Lawrence S. Ukeiley +2
We present a phase-based framework for reducing the pressure fluctuations within a spanwise-periodic supersonic turbulent cavity flow with an incoming free-stream Mach number of 1.…
Leveraging three-dimensionality for navigation in bluff-body wakes
Vedasri Godavarthi, Kartik Krishna, Steven L. Brunton +1
Biological flyers and swimmers navigate in unsteady wake flows using limited sensory abilities and actuation energies. Understanding how vortical structures can be leveraged for en…
Influence of three-dimensionality on wake synchronization of oscillatory cylinder
Youngjae Kim, Vedasri Godavarthi, Laura Victoria Rolandi +2
We investigate the effect of three-dimensionality on the synchronization characteristics of the wake behind an oscillating circular cylinder at Re = 300. Cylinder oscillations in r…
Optimal waveform for fast synchronization of airfoil wakes
Vedasri Godavarthi, Yoji Kawamura, Kunihiko Taira
We obtain an optimal actuation waveform for fast synchronization of periodic airfoil wakes through the phase reduction approach. Using the phase reduction approach for periodic wak…
Adjoint-based phase reduction analysis of incompressible periodic flows
Yoji Kawamura, Vedasri Godavarthi, Kunihiko Taira
We establish the theoretical framework for adjoint-based phase reduction analysis for incompressible periodic flows. Through this adjoint-based method, we obtain spatiotemporal pha…
