An Experimental Investigation on Brush Seal Hysteresis

Brush seal represents a compliant seal configuration. Brush seal offers better leakage performance than traditional labyrinth seal. However, hysteresis occurs due to the bristles to bristles friction force and the bristles to plate friction force. The phenomenon adversely affects the leakage performance of brush seal. In this paper, the influence of brush bristles and the plate on the brush seal hysteresis was investigated by contact force testing.
