In order to effectively select the position of the spiral groove and determine the factors affecting the gas film sealing performance, the influence of the position characteristics of the spiral groove on the performance of the film seal was simulated in this study. With theoretical analysis and ANSYS modeling software, this paper modeled the pressure field model in two states and the two kinds of gas film structure models, including static ring slotting and dynamic ring slotting. On this basis, the static pressure distribution and shear stress distribution under static ring groove and dynamic ring groove structure were studied by FLUENT software simulation, and the influence of different operating parameters on cylindrical gas film sealing performance was further analyzed. The simulation results showed that the gas film model of the static ring groove was slightly better than the gas film model of the dynamic ring groove, and the pressure difference and air viscosity had a significant effect on the gas film sealability.

Key words: spiral groove, sealing performance, pressure field model, static ring groove, dynamic ring slotting
