Abstract :
A two-phase flow expander modified by an air helical compressor has been successfully tested, making it possible to realize the triangle cycle, e.g. a total flow power system in the wet-vapor region. A total flow system using organic working fluid is introduced. A thermodynamic analysis of the system is presented, and it is compared with other common organic systems. The performance characteristics of a 500-kW geothermal power generating unit using the organic total flow method are presented
