- 摘要：
- Purpose – The purpose of this paper is to investigate the effect of boundary slip on hydrodynamic performance of liquid film seal considering
cavitation.
Design/methodology/approach – A mathematical model of liquid film seal with slip surface was established based on the Navier slip model and
Jakobsson–Floberg–Olsson (JFO) boundary condition. Liquid film governing equation was discretized by the finite difference method and solved by
the SOR relaxation iterative algorithm and the hydrodynamic performance parameters of liquid film seal were obtained considering boundary slip
and cavitation.
Findings – The results indicate that the values of performance parameters are affected significantly by the slip length under the condition of high
speed and low differential pressure.
Originality/value – The performances of liquid film seal are investigated considering slip surface and cavitation. The results presented in the study
are expected to provide a theoretical basis to improve the design method of liquid film seal.
