Probabilistic neural network-based reduced-order surrogate for fluid flows
Kai Fukami, Romit Maulik, Nesar Ramachandra +2
In recent years, there have been a surge in applications of neural networks (NNs) in physical sciences. Although various algorithmic advances have been proposed, there are, thus fa…
Aerodynamic characterization of low-aspect-ratio swept wings at
Kai Zhang, Kunihiko Taira
We perform unsteady three-dimensional direct numerical simulations to study the aerodynamic characteristics of finite-aspect-ratio swept wings with a NACA 0015 cross-section at a c…
Phase-locking of laminar wake to periodic vibrations of a circular cylinder
M. A. Khodkar, Joseph T. Klamo, Kunihiko Taira
Phase synchronization between the vortex shedding behind a two-dimensional circular cylinder and its vibrations is investigated using the phase-reduction analysis. Leveraging this…
Resolvent analysis of an airfoil laminar separation bubble at Re = 500,000
Chi-An Yeh, Stuart I. Benton, Kunihiko Taira +1
We perform resolvent analysis to examine the perturbation dynamics over the laminar separation bubble (LSB) that forms near the leading edge of a NACA 0012 airfoil at a chord-based…
Phase-synchronization properties of laminar cylinder wake for periodic external forcings
Mohammad Amin Khodkar, Kunihiko Taira
We investigate the synchronization properties of the two-dimensional periodic flow over a circular cylinder using the principles of phase-reduction theory. The influence of harmoni…
Network broadcast analysis and control of turbulent flows
Chi-An Yeh, Muralikrishnan Gopalakrishnan Meena, Kunihiko Taira
We present a network-based modal analysis technique that identifies key dynamical paths along which perturbations amplify over a time-varying base flow. This analysis is built upon…
