Abstract:

This paper deals with theoretical analysis of flow induced instability force due to labyrinth seal. That is, an approximate solution is given for the partial differential equation representing the flow in labyrinth seal and it is compared with the finite difference method which was proposed in the previous report in order to verify the accuracy of both methods. Then the effects of difference of inlet and outlet pressures of the seal, deflection of pressure and mass flow from the steady state, rotor diameter, seal clearance, seal interval and seal number on the flow induced force of the seal are investigated and it is known that some of these factors are very influential on the flow induced force.
