15. Gas turbine engine

When a volume of air is compressed

  • heat is gained.
  • no heat is lost or gained.
  • heat is lost.

Explanation from PART66Online

Compressing a gas does work on it and raises its internal energy, so its temperature and heat content increase. This is why compressor discharge air is hot; an isothermal process (no temperature change) would require continuous heat removal, which does not occur in a turbine compressor.
