BraytonIdeal:

Path: Thermal/ThermalAnalysis

% Ideal Brayton cycle
 Computes the efficiency, mass flow and temperatures. This power plant
 has a single compressor and turbine. Both are 100% efficient.

 The cycle points are

 1 - compressor inlet
 2 - compressor outlet
 3 - turbine inlet
 4 - turbine outlet

 Note: t2 = t4 in this ideal cycle.

 Type BraytonIdeal for a demo comparing helium, nitrogen and carbon
 dioxide.
