柱面气膜密封槽底导流织构性能提升及作用规律研究
Research on sealing performance improvement and functional rule of diversion texture at bottom of cylindrical gas film seal groove
摘要
Abstract
Studying how to improve the stability of the cylindrical gas film seal is crucial to ensure the safe operation of such seals at a high speed and under high pressure working conditions.In view of the fact that the diversion texture can effectively improve the stability of the system,this paper design a certain number and shape of the diversion structure at the bottom of the cylindrical gas film seal groove,with the effect of the diversion structure on the sealing performance of the cylindrical gas film seal under different working conditions systematically studied.The results show that the diversion texture has a good diversion effect on the micro scale flow field of cylin-drical gas film seal,and that the maximum pressure and high pressure area are significantly in-creased.Under certain working conditions and leakage conditions,the diversion texture can sig-nificantly improve the opening force,cylindrical gas film seal with diversion textures can signifi-cantly reduce the variance of pressure fluctuation in micro scale flow field at a high speed and un-der high pressure working conditions;the higher the speed,the more significant the disturbance suppression effect.关键词
