Abstract

This contribution describes the development of a discrete adjoint solver for the harmonic balance method using the technique of algorithmic differentiation by operator overloading. Harmonic balance is a nonlinear frequency domain method which is suitable to simulate time dependent periodic phenomena as they occur for example in turbomachinery flows. The adjoint solver is implemented in the framework of an industrial turbomachinery flow solver and applied in this work to compute sensitivities of aeroelastic forces with respect to geometric changes of the blades in a turbine.
