PDF Comparison of Leakage Between a Labyrinth Seal and An All Metal ...
(to 300°C) show the HALOTM seal leaks 50% or less than the labyrinth seal. For pressure ratios (P s/Pa) >, the HALOTM seal leaks ~¼ the flow in a labyrinth seal, thus demonstrating its excellent sealing characteristics. Moreover, tests with the novel seal proceeded to higher pressure ratios (max. Ps/Pa=8), a
