Forcing-informed resolvent analysis: Identification of input-output relations in self-sustained flows
Yuta Iwatani, Kunihiko Taira, Soshi Kawai
We present a forcing-informed (FI) resolvent analysis framework to identify input-output relations for statistically stationary self-sustained unsteady flows. The central idea of t…

Compact representation of transonic airfoil buffet flows with observable-augmented machine learning
Kai Fukami, Yuta Iwatani, Soju Maejima +2
Transonic buffet presents time-dependent aerodynamic characteristics associated with shock, turbulent boundary layer, and their interactions. Despite strong nonlinearities and a la…
