In this study, the thermodynamic analysis of the geothermal energy-assisted flash binary power generation cycle has been examined and compared according to different fluids. This study consists of a direct steam turbine and an organic Rankine cycle, and also performance comparison is investigated using nbutane, isobutane, and isopentane working fluids in the organic Rankine cycle. The energy and exergy efficiencies as well as the total irreversibility of the proposed system are investigated for three different fluids. In addition, the effects of changes in parameters such as environmental temperature, geothermal water outlet temperature, and pressure values on system efficiencies and power generation are investigated parametrically and the results are presented graphically. According to the analysis results, the total power generation rates are calculated as 3624 kW for n-butane, 3613 kW for isobutane, and 3495 kW for isopentane. Moreover, for the entire system, the highest energy and exergy efficiencies are calculated at 13.49% and 51.97% for the nbutane fluid, respectively.
