Process mode for the AA1 example simulation

The purpose of Process mode is to properly design the closed loop cycle so that we can set up a sensitivity analysis to determine the turbine outlet pressure and bypass rate that maximize the cycle efficiency. We can conduct case studies on the overall efficiency of the cycle by imposing various constraints in the system. We studied the following cases:

• Vary the turbine outlet pressure from 6 MPa to 15 MPa. Observe the impact on cycle efficiency and determine the optimal turbine outlet pressure.

• Use the optimal turbine outlet pressure from the previous case and vary the bypass flow from 10 kg/s to 60 kg/s. Observe the impact on cycle efficiency and determine the optimal bypass flowrate.

We model these cases by using the Scenario feature and we save individual snapshots for each constraint within the case. The following figure shows the list of Scenarios.
