Use of Parallel Coordinates for Post-Analyses of Multi-Objective Aerodynamic Design Optimisation in Turbomachinery

A novel approach for the post-analysis of design optimisation processes is suggested. The technique is based on parallel coordinates representation of multi-dimensional design spaces. By applying this methodology, the geometrical characteristics of optimum blade shapes of axial compressors responsible for improved behaviour of crucial o w characteristics possibly can be identied and classied according to their impact to the overall eciency of the turbomachine. Hence, geometrical features are directly associated with physical o w characteristics in highly complex aerodynamic domains. The main objective of this approach is to identify and reveal the physical mechanisms, which are responsible for highly ecien t turbomachines and which are obtainable by no other means, to the researchers and designers. Furthermore, the technique can be directly applied to any type of computational engineering design problem.
