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…
Computational study of numerical flux schemes for mesoscale atmospheric flows in a Finite Volume framework
Nicola Clinco, Michele Girfoglio, Annalisa Quaini +1
We develop, and implement in a Finite Volume environment, a density-based approach for the Euler equations written in conservative form using density, momentum, and total energy as…
Filter stabilization for the mildly compressible Euler equations with application to atmosphere dynamics simulations
Nicola Clinco, Michele Girfoglio, Annalisa Quaini +1
We present a filter stabilization technique for the mildly compressible Euler equations that relies on a linear or nonlinear indicator function to identify the regions of the domai…
