A high-order discontinuous Galerkin method for natural convection problems
No full textDiscontinuous Galerkin (DG) methods have proved to be very well suited for the construction of robust high-order numerical schemes on unstructured and possibly non conforming grids for a wide variety of problems. In this paper we consider natural convection flow problems and present a high-order DG method for their numerical solution. The governing equations are the incompressible Navier-Stokes (INS) with the Boussinesq approximation to represent buoyancy effects and the energy equation to describe the temperature field. The method here presented is an extension to natural convection flows of a novel high-order DG method for the numerical solution of the INS quations, recently proposed in [1]. The distinguishing feature of this method is the formulation of the inviscid interface flux which is based on the solution of local Riemann problems associated with the artificial compressibility perturbation of the incompressible Euler equations. The discretization of the viscous term follows the well established DG scheme named BR2 [2, 3]. The method is fully implicit and the solution is advanced in time using either a first order backward Euler or a second order Runge-Kutta scheme. To assess the capabilities of the DG method developed in this paper we computed second-, third-and fourth-order space-accurate solutions of several benchmark problems on natural convection in two-dimensional cavities
An implicit high-order discontinuous Galerkin method for steady and unsteady incompressible flows

the coupled Navier–Stokes and energy equations governing natural convection flows. The method is fully implicit and applies to the governing equations in primitive variable form. Its distinguishing feature is the formulation of the inviscid interface flux, which is based on the solution of local Riemann problems associated with the artificial compressibility perturbation of the Euler equations. The tight coupling between pressure and velocity so introduced stabilizes the method and allows using equal-order approximation spaces for both pressure and velocity. Since, independently of the amount of artificial compressibility added, the interface flux reduces to the physical one for vanishing interface jumps, the resulting method is strongly consistent. In this paper, we present a review of the method together with two recently developed issues: (i) the high-order DG discretization of
the incompressible Euler equations; (ii) the high-order implicit time integration of unsteady flows. The accuracy and versatility of the method are demonstrated by a suite of computations of steady and unsteady, inviscid and viscous incompressible flows

No full textNel contesto del candomblé di Bahia gli interdetti rituali, chiamati quizilas, svolgono un ruolo importante nella relazione di ordine simbolico che si costruisce tra l’iniziato al culto e le entità spirituali (orixás). La ricerca sul campo ha portato all’ipotesi che, oltre ai divieti associati ai pericoli di contaminazione e a quelli di natura collettiva, esistono interdizioni personali basate sulla sensibilità dell’adepto. Infatti, molti degli elementi associati ai fatti negativi vissuti dagli orixás nel tempo del mito producono, nell’attualità, delle reazioni negative negli iniziati, i quali possono avvertire disgusto, repulsione, intolleranza, soprattutto verso cibi. La relazione tra l’iniziato e l’orixá comporta, di fatto, una sorta de sovrapposizione di identità che si riflette nella sensibilità corporea dell’iniziato. Lo studio delle quizilas ha, pertanto, indicato l’importanza di una pratica etnografica incentrata sulla nozione di ‘corpo che sente’
