Acceleration of Gas Reservoir Simulation Using Proper Orthogonal Decomposition
Geofluids, 2018 High-precision and high-speed reservoir simulation is important in engineering. Proper orthogonal decomposition (POD) is introduced to accelerate the reservoir simulation of gas flow in single-continuum porous media via establishing a reduced-order model

Fusing Distributed Aerodynamic Data Using Bayesian Gappy Proper Orthogonal Decomposition
AIAA AVIATION 2021 FORUM, 2021 During the development of an aircraft, a multitude of aerodynamic data is required for different flight conditions throughout the flight envelope. Nowadays, a large portion of this data is routinely acquired by Computational Fluid Dynamics simulations ...

Proper orthogonal decomposition for optimality systems [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2008 The authors consider optimal control problems of the form \[ \min J(y,u)\quad\text{s.t. }y_t(t)= F(y(t))+ B(u(t)),\;y(0)= y_0, \] where the differential equation is considered in weak form in a separable Hilbert space of functions. For this problems, a method is proposed which avoids the problem of unmodelled dynamics in the proper orthogonal ...

Multiscale proper orthogonal decomposition (mPOD) of TR-PIV data—a case study on stationary and transient cylinder wake flows [PDF]
Measurement science and technology, 2020 Data-driven decompositions of particle image velocimetry (PIV) measurements are widely used for a variety of purposes, including the detection of coherent features (e.g. vortical structures), filtering operations (e.g.

Localised Proper Orthogonal Decomposition
Theoretical and Computational Fluid DynamicsProper Orthogonal Decomposition (POD) extracts an optimal orthonormal basis for reconstructing a sequence of data. This technique is widely used in fluid mechanics to construct reduced-order models for physical analysis, modelling, estimation, and control.

Understanding Cavity Flows Using Proper Orthogonal Decomposition and Signal Processing
Journal of Algorithms & Computational Technology, 2010 Computational Fluid Dynamics (CFD) is increasingly being used to analyse complex flows. However, to perform a comprehensive analysis over a given time period, a large amount of data is provided and therefore a method for reducing the storage requirements
