Comparison of Flow Behavior in Saccular Aneurysm Models Using Proper Orthogonal Decomposition
Fluids, 2022 Aneurysms are abnormal ballooning of a blood vessel. Previous studies have shown presence of complex flow structures in aneurysms. The objective of this study was to quantify the flow features observed in two selected saccular aneurysm geometries over a ...

Proper Orthogonal Decomposition Based Turbulence Modeling [PDF]
, 1992 An analysis of the near-wall behavior of the proper orthogonal decomposition (POD) eigenfunctions derived from direct numerical simulation (DNS) of channel flow is performed. Consistent with previous studies, a low order multi-mode reconstruction of the kinetic energy and Reynolds shear stress suffices.

On the Wake Dynamics of an Oscillating Cylinder via Proper Orthogonal Decomposition
Fluids, 2022 The coherent structures and wake dynamics of a two-degree-of-freedom vibrating cylinder with a low mass ratio at Re=5300 are investigated by means of proper orthogonal decomposition (POD) of a numerical database generated using large-eddy simulations ...

PySPOD: A Python package for Spectral Proper Orthogonal Decomposition (SPOD)
Journal of Open Source Software, 2021 Large unstructured datasets may contain complex coherent patterns that evolve in time and space, and that the human eye cannot grasp. These patterns are frequently essential to unlock our understanding of complex systems that can arise in nature, such as

Robust spectral proper orthogonal decomposition
Computer Physics CommunicationsExperimental measurements often present corrupted data and outliers that can strongly affect the main coherent structures extracted with the classical modal analysis techniques. This effect is amplified at high frequencies, whose corresponding modes are more susceptible to contamination from measurement noise and uncertainties.
