Resolvent-based estimation and control of a laminar airfoil wake
Junoh Jung, Rutvij Bhagwat, Aaron Towne
We develop an optimal resolvent-based estimator and controller to predict and attenuate unsteady vortex shedding fluctuations in the laminar wake of a NACA 0012 airfoil at an angle…

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…
