Optimal frequency resolution for spectral proper orthogonal decomposition
Liam Heidt, Tim Colonius
We demonstrate that accurate computation of the spectral proper orthogonal decomposition (SPOD) critically depends on the choice of frequency resolution. Using both artificially ge…
An adaptive lattice Green's function method for external flows with two unbounded and one homogeneous directions
Wei Hou, Tim Colonius
We solve the incompressible Navier-Stokes equations using a lattice Green's function (LGF) approach, including immersed boundaries (IB) and adaptive mesh refinement (AMR), for exte…
The effect of flight on a turbulent jet: coherent structure eduction and resolvent analysis
Igor A. Maia, Liam Heidt, Ethan Pickering +3
We study coherent structures in subsonic turbulent jets subject to a flight stream. A thorough characterisation of the effects of a flight stream on the turbulent field was recentl…
Linear Analysis of Boundary-Layer Instabilities on a Finned-Cone at Mach 6
Daniel B. Araya, Neal P. Bitter, Bradley M. Wheaton +8
Boundary-layer instabilities for a finned cone at Mach=6, [m], and zero incidence angle are examined using linear stability methods of varying fidelity…
A quantitative comparison of phase-averaged models for bubbly, cavitating flows
Spencer H. Bryngelson, Kevin Schmidmayer, Tim Colonius
We compare the computational performance of two modeling approaches for the flow of dilute cavitation bubbles in a liquid. The first approach is a deterministic model, for which bu…
A strongly-coupled immersed-boundary formulation for thin deforming surfaces, with application to elastic beams
Andres Goza, Tim Colonius
We present a strongly-coupled immersed-boundary method for flow-structure interaction problems involving thin deforming bodies. The method is stable for arbitrary choices of solid-…
