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 are 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 (ТVЗ-117).
