Wave interactions in a screeching jet
Ali Farghadan, Jayson Beekman, Petronio Nogueira +2
We use a series of global models to investigate the linear and nonlinear interactions between shock cells, Kelvin-Helmholtz waves, guided jet modes, and other fluctuations in a scr…

Efficient harmonic resolvent analysis via time-stepping
Ali Farghadan, Junoh Jung, Rutvij Bhagwat +1
We present an extension of the RSVD- algorithm initially developed for resolvent analysis of statistically stationary flows to handle harmonic resolvent analysis of time-perio…

Scalable resolvent analysis for three-dimensional flows
Ali Farghadan, Eduardo Martini, Aaron Towne
Resolvent analysis is a powerful tool for studying coherent structures in turbulent flows. However, its application beyond canonical flows with symmetries that can be used to simpl…
