One-way FSI simulation of the phase and the geometric parameters of the model of compressor blades on the oscillating gas-dynamic processes

Abstract

The paper presents the results of numerical simulations to assess the impact of the phase shifts and the geometric design parameters on oscillations in inter-blade channel model compressor gas pumping unit. The blades are considered to be cantilevered plate. At low flow rates and at different angles of phase shift between oscillations of neighboring blades investigated gasdynamic forces acting on the structure. It is shown that the phase shift between the change in the corresponding gas-dynamic forces acting on the blades and vanes oscillations of depends on the phase shift between the oscillations of of the blades.
