Generalisation of the Spectral Difference scheme for the diffused-interface five equation model
Niccolò Tonicello, Guido Lodato, Matthias Ihme
The present work focuses on the generalisation of the Spectral Difference (SD) scheme to the reduced Baer-Nunziato system known as five-equation model for the simulation of two imm…

Enhancing non-intrusive Reduced Order Models with space-dependent aggregation methods
Anna Ivagnes, Niccolò Tonicello, Paola Cinnella +1
In this manuscript, we combine non-intrusive reduced order models (ROMs) with space-dependent aggregation techniques to build a mixed-ROM. The prediction of the mixed formulation i…

A high-order diffused-interface approach for two-phase compressible flow simulations using a Discontinuous Galerkin framework
Niccolò Tonicello, Matthias Ihme
A diffused-interface approach based on the Allen-Cahn phase field equation is developed within a high-order Discontinuous Galerkin framework. The interface capturing technique is b…
