The turbomachine industry is increasingly interested in developing automated design procedures that are able to summarize their current design experience, to take into account the manufacturing limitations and to define new rules for improving their machines’ performance. In this paper, a strategy for the parametric analysis and optimization of transonic centrifugal impellers was developed, using the technique of the Design of Experiments coupled with a 3–D fluid-dynamic solver. The geometrical parameterization was conducted using Bezier curves and a few geometrical parameters, chosen after a screening analysis in order to determine the most significant ones. The range of variation of the parameters was defined taking into account the manufacturing requirements. The analysis of the influence of such parameters on the main impeller performance was subdivided into two steps: first, the effect of the parameters acting on the blade shape was investigated and an optimum configuration was chosen, then the influence of three functional parameters was analyzed, fixing the already optimized variables. The whole strategy aimed at an industrial design approach, and attention was focused on the time required in the design process. From the present analysis it is possible not only to define an optimum geometry, but also to understand the influence of the input parameters on the main machine performance.
