Abstract

Abstract: Based on the hydrodynamics, the air exciting – vibration force of turbomachinery caused by clearance is studied by using the momentum theorem. A computational formulation consisted of the design parameters of vane is educed and it has solved the difficult of selecting efficiency factor in Alford formulation. It can be seen that the presented formulation is correct and the computational result is believable.

Key words: Air - flow, Dynamics, Exciting – vibration force, Rotor
