Physical modeling of the labyrinth seal

A series of special studies operational and geometrical parameters effect on the maze, namely the quantities of the packed differential pressure, speed, the magnitude of the eccentricity, radial gap, ets., taking into account the criteria of design of labyrinth compressions and scale factor have been made. Existence of dependence of the leakage coefficient of a labyrinth seal from shaft speed, and from the quantities of the packed differential pressure before and behind labyrinth seals eccentricity is examined. Generalization use of Re and Eu criteria is offered, the criteria equation for flow seal coefficient for similar seals is received in case of different regime parameters.
