Analisi Dimensionale e Modellistica Fisica: Principi e applicazioni alle Scienze Ingegneristiche

Los angeles razionalizzazione delle scienze ha avuto un grande impulso con l’avvento e il consolidarsi dei concetti dell’Analisi Dimensionale, accanto alla quale si ? sviluppata l. a. modellistica fisica. Al pace in cui gli elaboratori non erano disponibili o non erano accessibili, l. a. modellistica fisica rimaneva l’unico strumento in line with affrontare e risolvere numerosi problemi di Ingegneria; non a caso l. a. maggior parte delle pubblicazioni scientifiche nel settore ?

For Re=5000, the coalescence happens earlier in comparison with the Re=9400 case: for the lower Re-number the vortices coalesce already after 3 sleepthroughs. This change can be compared with results for the fully inviscid follow case calculation that was conducted with the same CABARET Euler method. In the latter case the vortices manage to undergo 6 sleep-through events before coalescence. The capability of the CABARET model to capture the qualitative differences between the Re=9400 and the fully inviscid solution is noted as a good indication of how low-dissipative the method is.

One notable exception is the so-called Compact Accurately Adjusting high-Resolution Technique (CABARET) (Karabasov and Goloviznin, 2009). CABARET is the extension of Upwind Leapfrog (UL) methods (Iserlis, 1986; Roe, 1998; Kim, 2004; Tran and Scheurer, 2002) to non-oscillatory conservative schemes on staggered grids with preserving low dissipative and low dispersive properties. CABARET is an explicit conservative finitedifference scheme with second-order approximation in space and time and it is found very efficient in a number of Computational Fluid Dynamics (CFD) problems, (Karabasov and Goloviznin, 2007; Karabasov et al, 2009).

In the latter, the governing fluid flow equations are solved in a non-conservative form and the advected vortex solution is regularly reinitialised on a Eulerian grid to reduce the complexity of thin vorticity filaments and stabilise the solution. In the present subsection, the problem of counter-rotating vortices is solved on a fixed Eulerian grid for the range of Reynolds numbers, Re=5000-10000 with the conservative Navier-Stokes CABARET method. Fig. 8 shows the problem setup. Four viscous-core counter-rotating vortices are initiated in an open domain.
