Design Optimization of Customizable Centrifugal Industrial blowers for gas turbine power plants

Vincenzo Castorani (Università Politecnica delle Marche)

The paper presents an approach for the efficiency optimization of large and customizable centrifugal industrial blowers for gas turbine air supply. The design variables investigated in this study were the blades quantity, orientation and shape. The proposed optimization method employed in modeFRONTIER has been used for the design optimization of a blower for gas turbine power plant. The response surfaces allowed defining correlation between design variables and efficiency. The optimized design was 18 % more efficient than the original one.
