【Abstract】 Described was a high speed small-sized turbine applicable for organic Rankine cycles(ORC).With an electrically heated oil heater serving as the heat source and the circulating cooling water as the heat sink,a testing platform was set up for organic Rankine cycles.On the above-mentioned platform,a small-sized high speed turbine was tested and a performance analysis was performed with R123 serving as the circulating working medium.The research results show that when the rotating speed of the turbine is 24000 r/min,the adiabatic inner coefficiency of the turbine can hit 0.68.更多还原
