Reduced order modelling method via proper orthogonal decomposition (POD) for flow around an oscillating cylinder

Journal of Fluids and Structures, 2010
Abstract This paper presents reduced order modelling (ROM) in fluid–structure interaction (FSI). The ROM via the proper orthogonal decomposition (POD) method has been chosen, due to its efficiency in the domain of fluid mechanics. POD-ROM is based on a low-order dynamical system obtained by projecting the nonlinear Navier–Stokes equations on a ...

Application of Proper Orthogonal Decomposition (POD) to inverse problems in saturated groundwater flow

Advances in Water Resources, 2011
Abstract We develop a new Proper Orthogonal Decomposition (POD) reduced order model for saturated groundwater flow, and apply that model to an inverse problem for the hydraulic conductivity field. We use sensitivities as the POD basis. We compare the output when the optimizer uses the reduced order model against results obtained with a full PDE based

PROPER ORTHOGONAL DECOMPOSITION (POD) OF A CLASS OF VIBROIMPACT OSCILLATIONS

Journal of Sound and Vibration, 2001
Abstract This study employs the method of proper orthogonal decomposition (POD), also known as the Karhunen–Loeve (K–L) method, to extract dominant coherent structures (modes that approximate the system behavior) from time-series data. These mode shapes can be used in a Galerkin reconstruction process to obtain lower dimensional models for the ...

Order Reduction by Proper Orthogonal Decomposition (POD) Analysis

2004
The method of proper orthogonal mode decomposition (POD) or KarhunenLoeve decomposition (KLD) is a means of extracting spatial information from a set of time-series data available from a set of sensing locations over a domain. The POD can be used to obtain low-dimensional models or discrete or distributed dynamical systems by computing an orthogonal ...

An extraction of the dominant rotor-stator interaction modes by the use of Proper Orthogonal Decomposition (POD)

Journal of Thermal Science, 2006
The Proper Orthogonal Decomposition method is applied to the instantaneous velocity field within the rotor-stator inter-row region of a high-speed high-pressure centrifugal compressor. The processed data come from experiments and numerical simulations.
