Computer simulation of a viscous channel flow

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.

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.
