Resolvent-based estimation of a turbulent wake
Junoh Jung, Aaron Towne
We present a resolvent-based framework for estimating turbulent velocity fluctuations in the wake of a spanwise-periodic NACA0012 airfoil at Mach 0.3, Reynolds number 23,000, and a…
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…
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…
