A Random Matrix Approach for Quantifying Model-Form Uncertainties in Turbulence Modeling
Heng Xiao, Jian-Xun Wang, Roger G. Ghanem
With the ever-increasing use of Reynolds-Averaged Navier--Stokes (RANS) simulations in mission-critical applications, the quantification of model-form uncertainty in RANS models ha…

Reduced Wiener Chaos representation of random fields via basis adaptation and projection
Panagiotis Tsilifis, Roger Ghanem
A new characterization of random fields appearing in physical models is presented that is based on their well-known Homogeneous Chaos expansions. We take advantage of the adaptatio…

Data-driven probability concentration and sampling on manifold
Christian Soize, Roger Ghanem
A new methodology is proposed for generating realizations of a random vector with values in a finite-dimensional Euclidean space that are statistically consistent with a data set o…
