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.…
Improved approximations to the Wagner function using sparse identification of nonlinear dynamics
Scott T. M. Dawson, Steven L. Brunton
The Wagner function in classical unsteady aerodynamic theory represents the response in lift on an airfoil that is subject to a sudden change in conditions. While it plays a fundam…
Integrating multi-fidelity blood flow data with reduced-order data assimilation
Milad Habibi, Roshan M. D'Souza, Scott T. M. Dawson +1
High-fidelity patient-specific modeling of cardiovascular flows and hemodynamics is challenging. Direct blood flow measurement inside the body with in-vivo measurement modalities s…
From unsteady to quasi-steady dynamics in the streamwise-oscillating cylinder wake
Maysam Shamai, Scott T. M. Dawson, Igor Mezić +1
The flow around a cylinder oscillating in the streamwise direction with a frequency, , much lower than the shedding frequency, , has been relatively less studied than the…
