Abstract

An adjoint preprocess for an adjoint-based turbomachinery design process is described and applied. Shape sensitivities are calculated using an adjoint elliptic mesh deformation tool. Calculation of sensitivities for the CAD parameters is performed using these shape sensitivities and deformed surface grids. The method is applied to the shape optimization process for a counter-rotating fan. Integrating the adjoint preprocess into the gradient evaluation results in a significantly reduced dependency of the computation time on the number of design parameters.
