Parametric profiling of 2d compressor rows for multicriteria optimisation task

Abstract

The specific approach to the parametric profiling of the 2D compressor blades during multicriteria optimisation is discussed in the paper. Special topology is presented where suction and pressure sides are described by Bezier curves. Recommendations are given for problem definition features during optimisation process together with results of particular tasks. Optimisation was realized with in-house codes for profiling, ANSYS CFX for CFD modelling and IOSO for automated multicriteria optimisation.
