12th European Conference on Turbomachinery Fluid dynamics & Thermodynamics
This paper describes the setup and validation of a process chain for aeroelastic sensitivity analysis using adjoint methods. In particular, the adjoint of an harmonic balance solver is applied to capture unsteady effects. The interaction between different blade rows is simulated by an external coupling of the adjoint harmonic balance solver with a steady adjoint solver. The adjoint process is applied to a turbine stage and the results are compared to finite differences of forward computations.
