A bifidelity sparse-grid surrogate model driven by a discrepancy indicator
Matteo Rosellini, Filippo Fruzza, Alessandro Mariotti +2
Sparse-grid approximations based on Lagrange polynomials are one of the staple methods for approximating functions that are high-dimensional and expensive to evaluate, e.g. in the…
Flashback propensity due to hydrogen blending in natural gas: sensitivity to operating and geometrical parameters
Filippo Fruzza, Rachele Lamioni, Alessandro Mariotti +2
Hydrogen has emerged as a promising option for promoting decarbonization in various sectors by serving as a replacement for natural gas while retaining the combustion-based convers…
Multigrid sequential data assimilation for the large-eddy simulation of a massively separated bluff-body flow
Gabriel Moldovan, Alessandro Mariotti, Laurent Cordier +3
The potential for data-driven applications to scale-resolving simulations of turbulent flows is assessed herein. Multigrid sequential data assimilation algorithms have been used to…
