An Iterative Proper Orthogonal Decomposition (I-POD) Technique with Application to the Filtering of Partial Differential Equations

The Journal of the Astronautical Sciences, 2013
In this paper, we consider the filtering of systems governed by partial differential equations (PDE). We adopt a reduced order model (ROM) based strategy to solve the problem. We propose an iterative version of the snapshot proper orthogonal decomposition (POD) technique, termed I-POD, to sequentially construct a single ROM for PDEs that is capable of ...

Efficient Extraction of Vortex Structures by Coupling Proper Orthogonal Decomposition (POD) and High–Dimensional Model Representation (HDMR) Techniques

Numerical Heat Transfer, Part B: Fundamentals, 2012
Spatially evolving and temporally developing fluid flow patterns are encountered in wide-spectrum fluid thermal problems. The time and length scales of eddies involved may vary over a few orders of magnitude. Often, simultaneous detection, identification, and characterization of small- and large-scale eddies, and persistent structures such as coherent ...

Reduction of the computational time and noise filtration in the IHCP by using the proper orthogonal decomposition (POD) method

International Communications in Heat and Mass Transfer, 2008
In this paper a comprehensive investigation is performed on the application of the proper orthogonal decomposition (POD) in solving the inverse heat conduction problems (IHCP's). Inverse heat conduction problems are those in which the boundary or the initial condition, or the physical properties are unknown; instead temperature measurements at some ...

Simplified modeling of self-excited rear axle wheel shimmy vibrations by using the Proper Orthogonal Decomposition (POD)

2019
Vehicles are subject to a variety of requirements, of which the technical objectives are only a subfield. In addition, the different sub-areas increasingly interact with each other, whereby the complexity of the development process of a vehicle continuously rises.
