Triglobal resolvent analysis of swept-wing wakes
Jean Hélder Marques Ribeiro, Chi-An Yeh, Kunihiko Taira
Through triglobal resolvent analysis, we reveal the effects of wing tip and sweep angle on laminar separated wakes over swept wings. For the present study, we consider wings with s…
Laminar vortex dynamics around forward-swept wings
Kai Zhang, Kunihiko Taira
Forward-swept wings offer unique advantages in the aerodynamic performance of air vehicles. However, the low-Reynolds-number characteristics of such wings have not been explored in…
Resolvent analysis on the origin of two-dimensional transonic buffet
Yoimi Kojima, Chi-An Yeh, Kunihiko Taira +1
Resolvent analysis is performed to identify the origin of two-dimensional transonic buffet over an airfoil. The base flow for the resolvent analysis is the time-averaged flow over…
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…
