Optimization of Compressor Blade Geometry for Efficiency and Pressure Ratio Under Strength Constraint

The article describes an example of design optimizing of gas turbine compressor blade row with coupled simulation (coupled gas dynamics and strength) using technology of fluid-structure-interaction simulation by ANSYS tools. Geometry model, gas-dynamic model, finite element model and optimization technology used in work are described in detail. Optimized design parameters obtained showed improvements of 8% in efficiency and 7% in pressure ratio over the baseline compressor without decrease in safety factor.Copyright © 2014 by ASME
