Mathematical Analysis for the Rational Large Eddy Simulation model
No full textIn this paper we consider the Rational Large Eddy Simulation model recently introduced by Galdi and Layton. We briefly present this model, which (in principle) is similar to
others commonly used, and we prove the existence and uniqueness of a class of strong solutions. Contrary to the gradient model, the main feature of this model is that it allows a better control of the kinetic energy. Consequently, to prove existence of strong solutions, we do not need subgrid-scale regularization operators, as proposed by Smagorinsky. We also introduce some breakdown criteria that are related to the Euler and Navier–Stokes equations
La modernità del pensiero di Matteo Angelo Galdi: la Rivoluzione, la democrazia, l'Europa
No full textIl saggio analizza le vicende in esilio di Matteo Angelo Galdi e, più specificamente, i suoi scritti sull'Europa, dai quali emerge un'idea di un'istituzione solidale capace di mettere i popoli e la pace al centro del dibattito politico. L'originalità del suo pensiero trae spunto dai valori democratici emersi durante la Rivoluzione francese, ma anche dalla sua esperienza di esule
