Abstract. In this paper, the performance of a turbocharger twin-entry radial in ow turbine is investigated analytically and experimentally under steady state, full and partial admission conditions. In this modeling, the mass ow rate, pressure ratio and eciency of the turbine are assumed unknown. The turbine geometry and the inlet total pressure and temperature are known, hence, the turbine performance characteristics can be obtained. In the turbocharger laboratory, performance characteristics of the turbine are determined, measuring the main parameters for various operating conditions. Comparing the model and experimental results shows good agreement. Also, considering the eect of test parameters on performance uncertainty, it shows that the pressure ratio has more in uence. Finally, the uncertainty of eciency decreases as the pressure ratio increases.
