SummaryIn this paper, a non‐intrusive stochastic model reduction scheme is developed for polynomial chaos representation using proper orthogonal decomposition. The main idea is to extract the optimal orthogonal basis via inexpensive calculations on a coarse mesh and then use them for the fine‐scale analysis.

Combustion and Flame, 2018
Abstract In this paper, non-intrusive polynomial chaos expansion (NIPCE) is used for forward uncertainty quantification and sensitivity analysis of thermoacoustic stability of two premixed flame configurations. The first configuration is a turbulent swirl combustor, modeled by the Helmholtz equation with an n − τ flame model.

International Journal of Engineering Systems Modelling and Simulation, 2010
The paper presents the computational results of an ongoing validation effort of two polynomial chaos methods used in the non-deterministic simulations of the transonic flow in the NASA Rotor 37 axial compressor. In the first stage, a code to code comparison on the geometry of the NASA Rotor 37 allows exploring different influences on the computed mean ...

Non-Intrusive Polynomial Chaos Approach for Nonlinear Aeroelastic Uncertainty Quantification
AIAA AVIATION 2022 Forum, 2022A point collocation nonintrusive polynomial chaos approach is presented for nonlinear aeroelastic uncertainty quantification analysis. A unique aspect of the approach is the use of a nonlinear frequency-domain harmonic balance aeroelastic solution methodology, which allows one to directly solve for the data points that comprise an aeroelastic Limit ...

Nonlinear Propagation of Orbit Uncertainty Using Non-Intrusive Polynomial Chaos
Journal of Guidance, Control, and Dynamics, 2013This paper demonstrates the use of polynomial chaos expansions for the nonlinear, non-Gaussian propagation of orbit state uncertainty. Using linear expansions in tensor products of univariate orthogonal polynomial bases, polynomial chaos expansions approximate the stochastic solution of the ordinary differential equation describing the propagated orbit,
