Proper Orthogonal Decomposition Closure Models for Fluid Flows: Burgers Equation
This paper puts forth several closure models for the proper orthogonal decomposition (POD) reduced order modeling of fluid flows. These new closure models, together with other standard closure models, are investigated in the numerical simulation of the Burgers equation. This simplified setting represents just the first step in the investigation of the new closure models. It allows a thorough as...
متن کاملProper Orthogonal Decomposition Technique for Transonic Unsteady Aerodynamic Flows
A new method for constructing reduced-order models (ROM) of unsteady small-disturbance ows is presented. The reduced-order models are constructed using basis vectors determined from the proper orthogonal decomposition (POD) of an ensemble of small-disturbance frequency-domain solutions. Each of the individual frequencydomain solutions is computed using an ef cient time-linearized ow solver...
متن کاملArtificial viscosity proper orthogonal decomposition
We introduce improved reduced-order models for turbulent flows. These models are inspired from successful methodologies used in large eddy simulation, such as artificial viscosity, applied to standardmodels created by proper orthogonal decomposition of flows coupled with Galerkin projection. As a first step in the analysis and testing of our new methodology, we use the Burgers equation with a s...
متن کاملAIAA 2000–2545 Airfoil Design Optimization Using Reduced Order Models Based on Proper Orthogonal Decomposition
This paper presents a method for inviscid airfoil analysis and design optimization that uses reduced order models to reduce the cost of computation. Strong emphasis is placed on obtaining reasonably accurate solutions to the Euler equations with computational costs which are far lower than those required by traditional Computational Fluid Dynamics (CFD) techniques. The design procedure presente...
متن کاملProper orthogonal decomposition & kriging strategies for design
Future Work Conclusions The aim of the following research is to therefore remove this obstacle to the application of kriging whilst developing a strategy for use at higher dimensions. The goal of an initial investigation was therefore to determine if these hyperparameters should be tuned after every update, and to what degree they should be tuned, in order for the model to remain effective. Thi...
