Through triglobal resolvent analysis, we reveal the effects of wing tip and sweep angle on
laminar separated wakes over swept wings. For the present study, we consider wings with …

Shock waves interacting with turbulent boundary layers on wings can result first in self-
sustained flow unsteadiness and eventually in structural vibration. Due to its importance to …

We design an open-loop active flow control for separated flows around a plunging circular
cylinder based on resolvent analysis. The cylinder is plunging at a Strouhal number of 0.36 …

Eigenvectors of the observability and controllability Gramians represent responsive and
receptive flow structures that enjoy a well-established connection to resolvent forcing and …

In the context of transition analysis, linear input–output analysis determines the worst-case
disturbances to a laminar base flow based on a generic right-hand-side volumetric/boundary …

Resolvent analysis is a powerful tool that can reveal the linear amplification mechanisms
between the forcing inputs and the response outputs about a base flow. These mechanisms …

A specialized mesh-free radial basis function-based finite difference (RBF-FD) discretization
is used to solve the large eigenvalue problems arising in hydrodynamic stability analyses of …

variant of resolvent analysis that identifies forcing and response modes that are sparse in …

During the last decade, forcing and response modes produced by resolvent analysis have
demonstrated great potential to guide sensor and actuator placement and design in flow …

Many physical questions in fluid dynamics can be recast in terms of norm constrained
optimisation problems; which in-turn, can be further recast as unconstrained problems on …
