ABSTRACT:
This study investigates the efficiency of Brayton cycle power plants under a variety of design configurations. The study is unique in that the range of cycle parameters and configurations examined is beyond that generally discussed in the open literature. The parameters and configurations
1. Open and closed air cycles
2. Optimum pressure ratio
3. Helium versus air working fluids
4. Turbine and compressor isentropic efficiencies
5. Recuperator effectiveness
6. Turbine inlet temperature
7. Heat rejection temperature
8. Pressure drop losses
9. With/without intercooling
10. With/without reheat
Equation derivations, a computer listing, and a hand calculator program listing are included in the appendices so that variations other than those presented in the report may be studied.
