Query: Non-Intrusive Polynomial Chaos Method Applied to Full-Order and Reduced
  Problems in Computational Fluid Dynamics: a Comparison and Perspectives   In this work, Uncertainty Quantification (UQ) based on non-intrusive
Polynomial Chaos Expansion (PCE) is applied to the CFD problem of the flow past
an airfoil with parameterized angle of attack and inflow velocity. To limit the
computational cost associated with each of the simulations required by the
non-intrusive UQ algorithm used, we resort to a Reduced Order Model (ROM) based
on Proper Orthogonal Decomposition (POD)-Galerkin approach. A first set of
results is presented to characterize the accuracy of the POD-Galerkin ROM
developed approach with respect to the Full Order Model (FOM) solver
(OpenFOAM). A further analysis is then presented to assess how the UQ results
are affected by substituting the FOM predictions with the surrogate ROM ones.
