This work focused on validating the Aspen HYSYS simulator for interpreting the regenerative Rankine cycle with intermediate overheating. Manual methods for interpreting the Rankine cycle are complex and are time consuming. Two representative cases were examined to validate the Aspen HYSYS simulator. The first case had a Rankine cycle with: 1) an open heater and 2) a closed heater with steam extraction in the low pressure turbine. The second case had three open heaters and three steam extractions: two in the high pressure turbine and one in the low pressure turbine. Validation of the Aspen HYSYS simulator showed discrepancies of 1.2% in relation to manual calculations. The Aspen HYSYS simulator was versatile for evaluating variables that can affect the thermal efficiency of the cycle. In conclusion, the Aspen HYSYS simulator can be employed for teaching and for analyzing the Rankine cycle.
