A Variational Formulation of Resolvent Analysis
Benedikt Barthel, Salvador Gomez, Beverley McKeon
The conceptual picture underlying resolvent analysis(RA) is that the nonlinear term in the Navier-Stokes(NS) equations provides an intrinsic forcing to the linear dynamics, a descr…
Kernel Learning for Robust Dynamic Mode Decomposition: Linear and Nonlinear Disambiguation Optimization (LANDO)
Peter J. Baddoo, Benjamin Herrmann, Beverley J. McKeon +1
Research in modern data-driven dynamical systems is typically focused on the three key challenges of high dimensionality, unknown dynamics, and nonlinearity. The dynamic mode decom…
Tollmien-Schlichting route to elastoinertial turbulence in channel flow
Ashwin Shekar, Ryan M. McMullen, Beverley J. McKeon +1
Direct simulations of two-dimensional channel flow of a viscoelastic fluid have revealed the existence of a family of Tollmien-Schlichting (TS) attractors that is nonlinearly self-…
Closing the loop: nonlinear Taylor vortex flow through the lens of resolvent analysis
Benedikt Barthel, Xiaojue Zhu, Beverley J. McKeon
We present an optimization-based method to efficiently calculate accurate nonlinear models of Taylor vortex flow. We use the resolvent formulation of McKeon & Sharma (2010) to mode…
Resolvent analysis of stratification effects on wall-bounded shear flows
M. A. Ahmed, H. J. Bae, A. F. Thompson +1
The interaction between shear driven turbulence and stratification is a key process in a wide array of geophysical flows with spatio-temporal scales that span many orders of magnit…
