11.4.1 Compression with Intercooling
Incorporation of an intercooler into the compressor reduces compressor work.
But on the other hand, air led to the combustion chamber needs more heating. An
additional effect is reduced cooling flow rate, as the cooling air becomes colder.
Intercooling at an early stage in the compression is advantageous for efficiency.
The positive effect may be understood by considering a cycle with intercooling as a
