Large Eddy Simulation of gravity currents with a high order DG method

Autor: Bassi, C., Abbà, A., Bonaventura, L., Valdettaro, L.

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 Element method. In particular, a DG-LES approach in which the filter op

Numerical analysis of frazil ice formation in turbulent convection

Autor: Abba', A., Montini, M., Pignagnoli, L., Valdettaro, L., Olla, P.

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-dimensional parameters governing the system. We model the mixture of ice crys

Waves attractors in rotating fluids: a paradigm for ill-posed Cauchy problems

In the limit of low viscosity, we show that the amplitude of the modes of oscillation of a rotating fluid, namely inertial modes, concentrate along an attractor formed by a periodic orbit of characteristics of the underlying hyperbolic Poincar\'e equ
