Question:

Using EES (or other) software, determine the effects of pressure ratio, maximum cycle temperature, regenerator effectiveness, and compressor and turbine efficiencies on the net work output per unit mass and on the thermal efficiency of a regenerative Brayton cycle with air as the working fluid. Air is at 100 kPa and 300 K at the compressor inlet. Also, assume constant specific heats for air at room temperature. Determine the net work output and the thermal efficiency for all combinations of the following parameters. Pressure ratio:
6, 10
Maximum cycle temperature:
1500, 2000 K
Compressor isentropic efficiency:
80, 100 percent
Turbine isentropic efficiency:
80, 100 percent
Regenerator effectiveness:
70, 90 percent
