摘      要：The recovery of low temperature heat sources is a hot topic in the *** ORC system can effectively use the low temperature heat *** its main output device,the performance of the turbine is very *** single stage transonic turbine has the characteristics of small size and large output *** this paper,the complete design process of a transonic centrifugal turbine with R245fa in low working temperature condition is *** the design conditions,the shaft power and the wheel efficiency of the centrifugal turbine can reach 1.12 MW and 83.61%,*** addition,a thermodynamic ORC cycle is presented and the off-design conditions of the turbine and its influence on the system are studied in *** results obtained in the present work show that the single-stage transonic centrifugal turbine can be regarded as a potential choice to be applied in small scale ORC systems.
