Numerical simulations of aeroelastic instabilities in a turbine-blade cascade by a modified Van der Pol model at running excitation

Numerical simulations of aeroelastic instabilities in a turbine-blade cascade by a modified Van der Pol model at running excitation

The onset and spread of flutter in a turbine blade cascade are numerically studied. Due to the application of the reduced-cascade model consisting of simple elements (springs, rigid bodies, linear dampers) and aeroelastic forces introduced by the analytical Van der Pol model, it is useful to study t...
