  "textContent": "A gas turbine system comprises a compressor (10) for compressing air, a combustor for burning the air compressed by the compressor and fuel, a turbine (14) driven by combustion gases produced from the combustor, and a spraying apparatus for adding water to working air at least upstream or in an intermediate stage of the compressor (10). A rotationally symmetric groove (50) or projection (54) is formed in an inner wall surface defining a channel through which the working air added with the water flows, or in a channel-defining surface of a rotor (36) or a casing of the gas turbine (14). A larger amount of water can be supplied to the compressor (10) while improving the reliability of the gas turbine (14).",
