This paper improves the conventional performance prediction model by correlating recirculation loss at the outlet of compressor impeller with its rotational speeds. The validation is carried out on a gasoline engine turbocharger compressor. The result shows that accuracy of the new model is greatly improved over the whole operating speeds, which brings possibility to the high accurate performance prediction in off design condition and a powerful tool for the matching between turbocharger and engine.
