Using adjoint CFD to quantify the impact of manufacturing variations on a heavy duty turbine vane

Abstract

We consider the evaluation of manufacturing variations to the aerodynamic performace of turbine vanes using the adjoint method. The empirical data is based on 102 white light scans from casted parts. We compare expensive calculations by the finite disfference method with cheap adjoint calculations and we find high correlations.
