Dynamical p-adaptivity for LES of compressible flows in a high order DG framework
Antonella Abbà, Luca Bonaventura, Alessandro Recanati +1
We investigate the possibility of reducing the computational burden of LES models by employing locally and dynamically adaptive polynomial degrees in the framework of a high order…
Direct and Large Eddy Simulation of three-dimensional non-Boussinesq gravity currents with a high order DG method
Caterina Bassi, Antonella Abbà, Luca Bonaventura +1
We present results of three-dimensional Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of turbulent gravity currents with a Discontinuous Galerkin (DG) Finite…
A priori tests of a novel LES approach to compressible variable density turbulence
Caterina Bassi, Antonella Abbà, Luca Bonaventura +1
We assess the viability of a recently proposed novel approach to LES for compressible variable density flows by means of a priori tests. The a priori tests have been carried out fi…
Large Eddy Simulation of gravity currents with a high order DG method
C. Bassi, A. Abbà, L. Bonaventura +1
This work deals with Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of turbulent gravity currents, performed by means of a Discontinuous Galerkin (DG) Finite E…
A locally p-adaptive approach for Large Eddy Simulation of compressible flows in a DG framework
Matteo Tugnoli, Antonella Abbà, Luca Bonaventura +1
We investigate the possibility of reducing the computational burden of LES models by employing local polynomial degree adaptivity in the framework of a high order DG method. A nove…
A DG Implementation of a Novel Hybrid RANS/LES Technique With RANS Reconstruction
Antonella Abbà, Massimo Germano, Michele Nini +1
A new hybrid RANS/LES technique, based on the hybrid filter proposed by Germano in 2004, has been studied. The novelty herein introduced is represented by the reconstruction of the…
Anisotropic dynamic models for Large Eddy Simulation of compressible flows with a high order DG method
Antonella Abbà, Luca Bonaventura, Michele Nini +1
The impact of anisotropic dynamic models for applications to LES of compressible flows is assessed in the framework of a numerical model based on high order discontinuous finite el…
Numerical analysis of frazil ice formation in turbulent convection
A. Abba', M. Montini, L. Pignagnoli +2
We study the first steps of ice formation in fresh water turbulent convection (frazil ice regime). We explore the sensitivity of the ice formation process to the set of non-dimensi…
