Peculiarities of Thermophysical Processes of “Wet Compression” in Power Units with Highly Atomized Water Injection and Their Influence on Power Units Operation

Gas-turbine units (with finely atomized water being injected into compressor) characteristics are discussed. Turbo-compressor group rotational speed variation and other factors are taken into account for twin-shaft units. Calculations were based on the mathematic model, which was verified by test results obtained at experimental Institute for High Temperatures unit GTU-1500 with twin-shaft engine (ТV3-117).
