Abstract
Most magnetic fluid seals are multitooth structures for the high sealing capacity. However, the pressure transfer mechanism in the multitooth magnetic fluid seal is only carried out through experimental methods. In this article, a simulation method is presented to solve the two-phase flow of magnetic fluid and air in the sealing clearance. The boundary of the magnetic fluid is obtained by a volume of fluid method. In addition, a planar multitooth magnetic fluid seal is presented to observe the magnetic fluid barrier and obtain the pressure change during the pressure transfer process. The result shows that the fluid barrier ruptures when the pressure difference exceeds the sealing capacity. The pressure is transferred chamber by chamber in the multitooth magnetic fluid seal.

多齿电磁流体密封中压力传递机理的模拟与实验研究
摘要
大多数磁性流体密封件是具有高密封能力的多齿结构。然而,多齿磁性流体密封件中的压力传递机制仅通过实验方法进行。在本文中,提出了一种模拟方法来解决密封间隙中磁性流体和空气的两相流。磁性流体的边界通过流体体积法获得。此外,提出了一种平面多齿磁性流体密封件,以观察磁性流体屏障并获得压力传递过程中的压力变化。结果表明,当压力差超过密封能力时,流体屏障破裂。压力在多齿磁性流体密封件中逐腔传递。
