Podczas badań numerycznych problemu eksploatacji uszczelnień szczelinowych dwupierścieniowych określono warunki pracy uszczelnienia wpływające na zachowanie stabilności statycznej i dynamicznej zespołu wirującego przy utrzymaniu podstawowej funkcji uszczelnienia, separacji przestrzeni o różnych ciśnieniach.

Słowa kluczowe
