Abstract
Combined Brayton-Rankine cycles for power generation are calculated using the modulated empirical formulas of gas and steam tables in a computer programme with accurate assumptions. Three computer programmes were created to calculate the thermodynamic properties of the working fluids and to evaluate the performance of combined Brayton-Rankine cycles. Also, many parameters were varied to study the effect of their variation on the peformance of the combined Brayton-Rankine cycle power plants. The computational results for existent power plants were compared with the actual data of those power plants, and an excellent agreement was obtained between them.
