Proper Orthogonal Decomposition as Surrogate Model for Aerodynamic Optimization
International Journal of Aerospace Engineering, 2016 A surrogate model based on the proper orthogonal decomposition is developed in order to enable fast and reliable evaluations of aerodynamic fields. The proposed method is applied to subsonic turbulent flows and the proper orthogonal decomposition is ...

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

Lagrangian proper orthogonal decomposition
Journal of Fluid MechanicsWe introduce a modal representation for Lagrangian trajectories in turbulence, termed Lagrangian proper orthogonal decomposition. An ensemble of particle trajectories is used to construct velocity time series, which are normalized independently for each trajectory to isolate fluctuations.

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.

Investigation of proper orthogonal decomposition for echo state networks
Neurocomputing, 2023 Echo State Networks (ESN) are a type of Recurrent Neural Network that yields promising results in representing time series and nonlinear dynamic systems. Although they are equipped with a very efficient training procedure, Reservoir Computing strategies, such as the ESN, require high-order networks, i.e., many neurons, resulting in a large number of ...

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
