Sketch-Based Resolvent Analysis [PDF]
AIAA AVIATION 2022 Forum, 2022 A significant hurdle in the adoption of resolvent analysis is the singular value decomposition (SVD) of the large linear operators involved. A matrix sketching algorithm is used to extract the primary forcing and response modes, with their associated ...

Acoustic resolvent analysis of turbulent jets [PDF]
International audienceWe perform a resolvent analysis of a compressible turbulent jet, where the optimisation domain of the response modes is located in the acoustic field, excluding the hydrodynamic region, in order to promote acoustically efficient ...

Resolvent analysis of a swimming foil [PDF]
This study employs resolvent analysis to explore the dynamics and coherent structures in the boundary layer of a foil that swims via a travelling wave undulation. A modified NACA foil shape is used together with undulatory kinematics to represent fish-like bodies at realistic Reynolds numbers ($ \mathit{Re} = 10,000 $ and $ \mathit{Re} = 100,000 $) in ...

On the Oseen-type resolvent problem associated with time-periodic flow past a rotating body [PDF]
, 2021 Consider the time-periodic flow of an incompressible viscous fluid past a body performing a rigid motion with non-zero translational and rotational velocity. We introduce a framework of homogeneous Sobolev spaces that renders the resolvent problem of the

Scalable resolvent analysis for three-dimensional flows [PDF]
Journal of Computational PhysicsResolvent 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 simplify the problem to inherently three-dimensional flows and other large systems has been hindered by the computational cost of computing resolvent modes. In particular, the CPU

Resolvent analysis of turbulent channel flow with manipulated mean velocity profile
Journal of Fluid Science and Technology, 2020 Using the resolvent analysis, we investigate how the near-wall mode primarily responsible for the friction drag is amplified or suppressed depending on the shape of the mean velocity profile of a turbulent channel flow.
