Abstract:

In order to improve centrifugal compressor performance predictive capability, an improved recirculation loss model in two-zone modeling system is presented in this paper. The new loss model correlates Reynolds number of the impeller with the recirculation loss. Performance prediction by the improved model is carried out on two turbochargers with different sizes based on COMPAL mode of the code Concepts. The result shows that predictive performance by improved model is in high accordance with experimental measurement. On the other hand, compared with the larger size compressor, the small one has a performance which is more likely to be influenced by Reynolds number.
