End-to-end optimization of subgrid scale models for discontinuous spectral element schemes based on the discrete adjoint method
Nicola Clinco, Niccolò Tonicello, Paola Cinnella +1
In computational fluid dynamics, Large Eddy Simulation (LES) offers a compelling balance between accuracy and computational cost by resolving large-scale flow structures while mode…
A data-driven study on Implicit LES using a spectral difference method
Nicola Clinco, Niccolò Tonicello, Gianluigi Rozza
In this paper, we introduce a data-driven filter to analyze the relationship between Implicit Large-Eddy Simulations (ILES) and Direct Numerical Simulations (DNS) in the context of…
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…
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…
