3.1.1.3 Project Results<br />
We have to run the reactor clusters in order because calculations of later clusters<br />
require information from the solution of the previous cluster. After finishing all four<br />
cluster runs, we want to see if the predicted mass flow rate and gas temperature at<br />
the exit of the last (fourth) reactor cluster match the gas turbine design point targets.<br />
The predicted mass flow rate of each combustor system, which is 1/6 of the total<br />
mass flow rate, and the turbine rotor inlet temperature can be found from the output<br />
file from the last cluster run (see Figure 3-4).<br />
