Abstract In this paper, a differential equation for wear volume of brush seal has been established and the theoretical model of wear volume has been obtained. Wear volume of a brush seal was a function of interference, pressure drop, rotating speed, gas temperature, inner diameter of brush seal, diameter of a bristle, lay angle of the bristle, and thickness of the bristle pack. Besides, abrasive resistance and mechanical property of bristle and coating materials could also influence significantly. Testing has been conducted to determine the correction factor in the model and verify the model, and the theoretical results were in good agreement with the experimental results.
