Turbocharger Design

The compressor and turbine wheel designs have the greatest influence on the turbocharger’s operational and performance characteristics. BorgWarner engineers perform finite element analysis (FEA) and computational fluid dynamics (CFD) to optimize wheel durability and performance based on the application needs. After several CFD iterations, performance is confirmed on a gas stand and tested per SAE standards.

Despite today's advanced computer technology and detailed calculation programs, it is testing which finally decides on the quality of the new aerodynamic components. The fine adjustment and checking of results is carried out on turbocharger test stands.
