Effect of fuel stratification length scale on thermodiffusively unstable lean hydrogen flames
Filippo Fruzza, Sofiane Al Kassar, Rachele Lamioni +2
Lean premixed hydrogen flames are highly susceptible to thermodiffusive instabilities, which generate complex cellular structures and enhance propagation speed. In practical combus…
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…
Three-dimensional numerical investigation of flashback in premixed hydrogen flames within perforated burners
Filippo Fruzza, Hongchao Chu, Rachele Lamioni +3
Predicting flashback represents a pivotal challenge in the development of innovative perforated burners for household appliances, especially for substituting natural gas with hydro…
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…
Renormalization-group techniques for single-field inflation in primordial cosmology and quantum gravity
Damiano Anselmi, Filippo Fruzza, Marco Piva
We study inflation as a "cosmic" renormalization-group flow. The flow, which encodes the dependence on the background metric, is described by a running coupling , which parametr…
