Effect of axial misalignment and tip clearance on the performance of double spiral seals

HIGHLIGHTS

• What: At present, the research on the spiral seal is mainly focused on the study of the mechanism and the study of the structural parameters. The research shows that with the increase of the tip clearance, the sealing performance of the spiral seal will gradually deteriorate from good to bad until leakage occurs. The research shows that the mixed spiral labyrinth seal is effective under both low pressure and high pressure. In this paper, the model of double_helix seal is established, and the model is shown in Fig 1, and then the fluid simulation calculation is carried . . .
