| Summary: | The goal of this work is to conduct a transient compressor blade row flow simulation
as part of blade flutter modeling. An integral step of blade flutter modeling is the calculation of
the aerodynamic damping factor as a function of the possible vibration mode shapes. Using
Fourier method, the number of blade passages required for transient flow analysis is kept to a
minimum of two for all vibration modes. In this work, a compressor rotor blade row is
considered. The vibration modes are obtained using ANSYS mechanical, then, unsteady flow
is obtained for vibrating blades with a harmonic motion. Work of the flow on the blade is
calculated and hence the aerodynamic damping is obtained. |
