Data-driven identification of coherent structures in gas-solid system using proper orthogonal decomposition and dynamic mode decomposition

The Physics of Fluids, 2022
Spatiotemporal coherent structures are critical in quantifying the hydrodynamics of dense gas-solid flows. In this study, two data-driven methods, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), are applied to identify and ...

Galerkin proper orthogonal decomposition-reduced order method (POD-ROM) for solving generalized Swift-Hohenberg equation

International journal of numerical methods for heat & fluid flow, 2019
Purpose The current paper aims to develop a reduced order discontinuous Galerkin method for solving the generalized Swift–Hohenberg equation with application in biological science and mechanical engineering. The generalized Swift–Hohenberg equation is a

Spectral Proper Orthogonal Decomposition of Unsteady Wall Shear Stress Under a Turbulent Separation Bubble

AIAA Journal, 2022
Spectral proper orthogonal decomposition (SPOD) is used to investigate the low-frequency behavior of a pressure-induced turbulent separation bubble (TSB) generated on a one-sided diffuser at a nominal velocity of 20 m/s. The input to the decomposition is
