The aim of the present work is to carry out a numerical and experimental analysis of fluid leakage in mechanical seals under static operating conditions. For the numerical estimation of leakage, a boundary element model was coupled with an adaptive mesh for solving the rough contact problem, and a finite volume method was employed for solving the fluid flow problem. The validation of the numerical approach and the experimental estimation of leakage were performed using a dedicated test bench capable of reproducing the behavior of the seal under various operating conditions.
L’obiettivo del seguente lavoro è quello di svolgere un’analisi numerica e sperimentale del trafilamento fluido in tenute meccaniche, in condizioni statiche. Per la stima numerica del trafilamento si è accoppiato un modello agli elementi di contorno, implementando una mesh adattiva per la risoluzione del problema di contatto rugoso ed un metodo ai volumi finiti per la risoluzione del problema fluido. La validazione dell’approccio numerico e la stima sperimentale del trafilamento sono state effettuate mediante un banco prova dedicato, in grado di riprodurre il comportamento della tenuta in diverse condizioni operative.

Abstract
The aim of the present work is to carry out a numerical and experimental analysis of fluid leakage in mechanical seals under static operating conditions. For the numerical estimation of leakage, a boundary element model was coupled with an adaptive mesh for solving the rough contact problem, and a finite volume method was employed for solving the fluid flow problem. The validation of the numerical approach and the experimental estimation of leakage were performed using a dedicated test bench capable of reproducing the behavior of the seal under various operating conditions.| File | Dimensione | Formato | |
