Abstract—Compressor’s pressure ratio (PR) is the main parameter that indicates turbocharger’s performance. Some tests are performed in order to measure pressure ratio and map the compressor’s performance. However, limits of test setups might not be appropriate for testing all performance scenarios in different operating conditions. Additionally, prototype production costs and tests on all conditions can be very expensive and time consuming. Hence, it is more economical and appropriate to measure the performance of turbocharger compressor via numerical methods. The purpose of this paper is to create numerical models of centrifugal turbocharger compressor in different Computational Fluid Dynamics (CFD) codes and validate the models with experimental data.
