<strong>13</strong>.6 Brayton Cycle with Intercooling<br />
When the compressor is divided into a low-pressure and a highpressure<br />
part, an intercooler can be installed between the two<br />
stages. In accordance with (<strong>13</strong>.12) cooling the air entering a compressor<br />
will result in a reduction of work required to compress the<br />
air; thus, a reduction in the second stage work will result with the<br />
addition of an intercooler. Since the turbine work is presumed<br />
unchanged and the compressor work is decreased by intercooling,<br />
the net work is increased and the thermal efficiency of the cycle<br />
is increased.<br />
The thermodynamic processes for compression with intercooling<br />
are shown in Figure <strong>13</strong>.9. The process 01-05' represents the
