摘要：

An effective finite difference method is adopted to calculate the pressure distribution of radial groove gas-lubricated face seals at slow speed condition. Some key parameters of seal performance, such as open force, gas film stiffness, and leakage rate are calculated. Effect of seal ring parameters on seal performance is also analyzed. Compared with the results of non-slip-flow condition, it is shown that the effect of slip flow should be considered when the gas seal is analyzed at slow speed.
