Abstract
This paper proposes an approach for the sensitivity computation of an aeroacoustic
problem via the solution of the continuous sensitivity equations. The equations are
derived by differentiating the coupled system (Navier-Stokes equations and the linearized
Euler equations) with respect to design parameters. The obtained acoustic sensitivity information
can be used to analyze the flow control variable’s influence on the acoustic field
or to calculate the gradient of an objective functional within aeroacoustic optimization
problems. The components of the coupled sensitivity solver are systematically verified.
