Modal Decomposition Analysis of Three-Dimensional Transonic Buffet Phenomenon on a Swept Wing
TL;DR: In this article, the dominant fluid structures and unsteady behavior of the three-dimensional transonic buffet phenomenon on a swept wing are clarified, focusing on a well-established buffet phenomenon.
Journal ArticleDOI
Spatiotemporal dynamics and early detection of thermoacoustic combustion instability in a model rocket combustor
TL;DR: The turbulence network, which consists of nodes and vertexes in weighted networks between vortices, can characterize the complex spatiotemporal structure of a flow field during thermoacoustic combustion instability.
Journal ArticleDOI
Preconditioned dynamic mode decomposition and mode selection algorithms for large datasets using incremental proper orthogonal decomposition
TL;DR: In this article, a simple and efficient framework of dynamic mode decomposition (DMD) and mode selection for large datasets has been proposed and applied to the analysis of three-dimensional flow around a circular cylinder.
Journal ArticleDOI
Numerical investigation of wake structures of an atmospheric entry capsule by modal analysis
TL;DR: In this paper, the authors investigated the flow structures behind an atmospheric entry capsule at Mach number 0.4 through an improved detached eddy simulation and a modal analysis and revealed relatively low-frequency peaks of St ≈ 0.016 and St = 0.17-0.2 in the aerodynamic coefficient variation, where St is the nondimensional frequency.
