Abstract
The purpose of this work is to optimize the stator shape
of an axial compressor, in order to maximize the global efficiency
of the machine, fixing the rotor shape. We have used a 3D
parametric mesh and the CFX-Tascflow code for the flow simulation.
To find out the most important variables in this problem, we have
run a preliminary series of designs, whose results have been
analyzed by a statistic tool. This analysis has helped us to
choose the most appropriate variables and their ranges in order to
implement the optimization algorithm more efficiently and rapidly.
For the simulation of the fluid flow through the machine, we have
used a cluster of 12 processors.
