OPTIMIZATION APPROAC H AND SOME RESULTS FOR 2D COMPRESSOR AIRFOIL

Abstract

Several optimization approaches are presented in the paper, and the results of each task depending on the optimization setup are compared and discussed in terms of physical behavior and convergence. The optimization problem is set up and solved for several 2D compressor airfoils with different inlet parameters. The airfoils were generated and their characteristics were built for optimized solutions from different optimization approaches. The novel topology for 2D compressor airfoil is proposed an and successfully utilized. The approach was tested for particular cases and showed a gain in efficiency and flow turning up to 15% (relative) compared with NACA-65 airfoils taken as the initial design.
