A Porous Media Leakage Model of Contact Mechanical Seals Considering Surface Wettability

The fluid leakage channel found in contact mechanical seals belongs to the microchannel category. Thus, upon further inspection, influence of surface wettability and other factors neglected previous studies becomes obvious. porous model considering presented this paper was based on Cassie slip theory. variations length velocity under various conditions were studied relationship between apparent angle established. Moreover, using media theory, theoretical rate considers depending parameters. observed parameters included angle, sealing medium pressure, viscosity coefficient, fractal dimension, maximum pore diameter. simulation results obtained proposed have shown that increases with increase angle. Particularly when pressure is small, more significant. Furthermore, via compared those existing models. comparison confirmed applicable necessity significantly affects calculation accuracy. lays a foundation for improving accuracy, making it easier both researchers practitioners suppress seals.
