problem statements are solved sequentially, and the simulation is
done on software like SMath or MathCAD.
The gas turbine system in Figure 1 is to be simulated.
Compressor and turbine characteristics are given in Figure 2 y
Figure 3 respectively. Use air as the working fluid. T1 is 100 F,
and 210 gal/hr of JP-4 (heat content 130 000 Btu/gal) fuel is used.
Assuming p2 = p3 and neglecting the effects of πΜπ on the mass flow
rate, complete the following in order: a) Generate curve fits for
π2 = π2(πΜ ) and πΈπ (πΜ ) b) Generate curve fits for πΜ = πΜ (π3,
π3 ) and πΈπ‘ = πΈπ‘ (π3, π3 ) c) Develop the system of equations
required to model the systems d) Simulate the system e) List the
steady-state value of all variables. f) What is the turbine exit
temperature? If the unit is an industrial gas turbine, examine the
potential for energy recovery from the exhaust gases.
