Sommario

Si presenta una soluzione numerica delle equazioni di Navier-Stokes bidimensionali in un condotto tra lastre parallelel in presenza di un diaframma forato al numero di Reynolds Re=1800. Si illustrano i grafici delle linee di corrente ottenute e si fa un confronto tra il coefficiente di portata calcolato e i risultati sperimentali.

Summary

A numerical solution of the two — dimensional Navier — Stokes equations for the flow in a duct between parallel plates in the presence of a diaphragm with an orifice at Reynolds number Re=1800 is presented. The plots of the resulting streamlines are illustrated and the computed discharge coefficient is compared with the experimental results.
