Statistical characterization of horizontal slug flow using snapshot proper orthogonal decomposition

Modeling of transitional channel flow using balanced proper orthogonal decomposition

We study reduced-order models of three-dimensional perturbations in linearized channel flow using balanced proper orthogonal decomposition BPOD . The models are obtained from three-dimensional simulations in physical space as opposed to the traditional single-wavenumber approach, and are therefore better able to capture the effects of localized disturbances or localized actuators. In order to a...

Proper Orthogonal Decomposition for Flow Calculations and Optimal Control in a Horizontal Cvd Reactor

Proper orthogonal decomposition (which is also known as the Karhunen Lo eve decomposition) is a reduction method that is used to obtain low dimensional dynamic models of distributed parameter systems. Roughly speaking, proper orthogonal decomposition (POD) is an optimal technique of nding a basis which spans an ensemble of data, collected from an experiment or a numerical simulation of a dynami...

Trust-region Proper Orthogonal Decomposition for Flow Control

The proper orthogonal decomposition (POD) is a model reduction technique for the simulation of physical processes governed by partial differential equations, e.g. fluid flows. It can also be used to develop reduced order control models. Fundamental is the computation of POD basis functions that represent the influence of the control action on the system in order to get a suitable control model....
