This model describes a gas turbine unit as a single model, including the interface and all equations, except the computation of the performance characteristics and of the exhaust composition.
Actual operating conditions are related to ISO standard conditions pnom and Tnom by the following relationship:
- HI_ISO = HI*sqrt(Tnom/gas.T)*(pnom/gas.p)
- ZLPout_ISO = ZLPout*sqrt(Tnom/gas.T)*(pnom/gas.p)
- wia_ISO = wia*pnom/gas.p*sqrt(gas.T/Tnom)
where HI is the heat input, ZLPout the zero loss power output and wia the air inlet flow.
Modelling options
This model has three different Medium models to characterize the inlet air, fuel, and flue gas exhaust.
