Sparsity-promoting methods for isolating dominant linear amplification mechanisms in wall-bounded flows

Scott T. M. Dawson, Jaime Prado Zayas, Barbara Lopez-Doriga

This work proposes a method to identify and isolate the physical mechanisms that are responsible for linear energy amplification in fluid flows. This is achieved by applying a spar…

Wavelet-based resolvent analysis of non-stationary flows

Eric Ballouz, Barbara Lopez-Doriga, Scott T. M. Dawson +1

This work introduces a formulation of resolvent analysis that uses wavelet transforms rather than Fourier transforms in time. Under this formulation, resolvent analysis may extend…

Sparse space-time resolvent analysis for statistically-stationary and time-varying flows

Barbara Lopez-Doriga, Eric Ballouz, H. Jane Bae +1

Resolvent analysis provides a framework to predict coherent spatio-temporal structures of largest linear energy amplification, through a singular value decomposition (SVD) of the r…

Linear and nonlinear Granger causality analysis of turbulent duct flows

Barbara Lopez-Doriga, Marco Atzori, Ricardo Vinuesa +3

This research focuses on the identification and causality analysis of coherent structures that arise in turbulent flows in square and rectangular ducts. Coherent structures are fir…

A sparsity-promoting resolvent analysis for the identification of spatiotemporally-localized amplification mechanisms

Barbara Lopez-Doriga, Eric Ballouz, H. Jane Bae +1

This work introduces a variant of resolvent analysis that identifies forcing and response modes that are sparse in both space and time. This is achieved through the use of a sparse…

Wavelet-based resolvent analysis for statistically-stationary and temporally-evolving flows

Eric Ballouz, Barbara Lopez-Doriga, Scott T. M. Dawson +1

This work introduces a formulation of resolvent analysis that uses wavelet transforms rather than Fourier transforms in time. This allows resolvent analysis to be extended to turbu…

Resolvent Analysis of laminar and turbulent duct flows

Barbara Lopez-Doriga, Scott T. M. Dawson, Ricardo Vinuesa

This work applies resolvent analysis to incompressible flow through a rectangular duct, in order to identify dominant linear energy-amplification mechanisms present in such flows.…
