On the Rayleigh-Taylor instability of a diffuse interface
Marildo Kola, Daniel Israel, Aaron Towne
We present a formulation for the linear stability of the miscible Rayleigh-Taylor instability, retaining viscosity, Fickian mass diffusion, and non-Boussinesq effects. Rather than…
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-period…
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…
Ambiguity in mean-flow-based linear analysis
U. Karban, B. Bugeat, E. Martini +6
Linearisation of the Navier-Stokes equations about the mean of a turbulent flow forms the foundation of popular models for energy amplification and coherent structures, including r…
