An advanced computer-aided engineering (CAE) system including a complete three-dimensional flow analysis has been developed for a centrifugal compressor. It is one of the most advanced computer fluid dynamics (CFD) in the world. Flow in compressor components is calculated and evaluated in this system in terms of the three-dimensional, viscous, compressible, turbulent and rotational flow. This aerodynamic CAE system has already been applied to the actual compressor design.
To improve efficiency, an automatic performance control system for a multi-stage centrifugal compressor was developed where the rotational speed and the vane setting angles were controlled by artificial intelligence (AI). Improved performance of a compressor with this computer control system was comfirmed under actual operation.
