ANALYSIS TO THE HYSTERESIS OF FINGER SEAL

Abstract

Abstract: The hysteresis effect of three finger seal configurations is analyzed under the condition of different pressure differential. Two phenomena is found that the finger seal with higher radial stiffness can generally reduce the hysteresis effect of sealing elements and that a finger seal configuration of low hysteresis and low radial stiffness can be achieved by creating reasonable finger shape-curve. A baseline finger seal with logarithen spiral I finger shape-curve is put forward which can be used as a foundation of further study for low hysteresis finger seal.
