In order to optimize turbo machine components it is necessary to describe the behaviour of multimodal objective functions (OF). Instead very time-consuming evaluations using a three-dimensional Navier–Stokes solver have to be performed to get the characteristics of these OF. In this study an Artificial Neural Network (ANN) is considered to use it as a performance predictor with the view to replace the evaluation of the objective function to speed up the optimization process.
