【Abstract】 The dissipation characteristic of labyrinth seal cavity is represented conventicnally by the kinetic energy carry - over coefficient. In this paper, it is expressed by the dissipation function which is canmonly used in fluid mechanica. With clear physical meaning, dissipation function can represent the characteristic of labyrinth cavity more properly. Finally, from the points of theory and application, the feasibility and reliability of the method are analyzed with the help of a through - flow and a crossed - flow labyrinth cavity as examples.更多还原
