Running flutter waves in the model of turbine blades cascade
Original language description
This contribution is connected with the paper on the previous conference, where the origin and properties of forced running waves produced by flowing steam through cascade of stationary and rotating wheels with different numbers of blades in the steam turbine were investigated. Due to the aero-elastic forces of this steam flow, these comparatively small vibrations can excite strong flutter running waves. Presented contribution is oriented on the analysis of dynamic properties of computational model of blades cascade, where the flutter is modelled by two types of Van der Pol self-excitation forces.
