摘要：
In this paper the performance characteristics of a turbocharger twin-entry radial inflow gas turbine with asymmetrical volute and rotor tip diameter of 73.6 mm in steady state and under full and partial admission conditions are investigated. The employed method is based on one dimensional performance prediction which is developed for partial admission conditions. Furthermore, this method is developed for the asymmetrical volute of the turbine considering the flow specifications. Experimental investigation of the research was carried out oil special test facilities under full and partial admission conditions for a wide range of speeds. A comparison of experimental and modeling results shows good agreement. Interestingly, the turbine maximum efficiency occurs when the shroud side inlet mass flow is higher than that of the hub side.
