Explore the effects of compressor pressure ratio (2 to 20 in increments) and mixture ratios (Helium and Xenon) between 0% and 90% by mole fraction of Xenon in increments of 10% to see the effects on net power, thermal efficiency, radiator area, and turbine inlet temperature of the closed Brayton cycle, subject to the following constraints
1. The reactor will apply a steady 300 kW as ?Qin ,
2. Fix the compressor inlet temperature to 300 K. Assume the radiator temperature is the average of T5 and T2.
3. The mass flow rate of the working fluid is 1 kg/s
Produce the following plots to help in describing the results:
1. Net output power (kWe) vs. compressor ratio with curves of constant Xe mole fraction.
2. Thermal efficiency vs. compressor ratio with curves of constant Xe mole fraction.
3. Turbine inlet temperature vs compressor ratio with curves of constant Xe mole fraction.
4. Radiator area vs compressor ratio with curves of constant Xe mole fraction.
The maximum allowable turbine inlet temperature in the real system is 2000K. Discuss the best choice(s) for operating conditions (mixture ratio of Xe and He, and compressor pressure ratio).
