原始语种摘要: Thermal efficiency of the ideal Carnot cycle is accepted to be highest of all reversible cycles. Heat is supplied at the highest process of temperature, and rejected at the lowest temperature. The reversible recuperative Joule-Brayton cycle, an ideal gas turbine cycle with heat recuperation, can also reach the Carnot efficiency when the pressure ratio is unity. In the evaporative gas turbine cycle (EGT-cycle), water is injected after the compressor and cools the charged air. More heat can be recuperated, this allows for higher thermal efficiencies. When the reversible recuperative Joule-Brayton cycle reaches the Carnot efficiency for a pressure ratio of unity, and the EGT efficiency is higher, then, it would be possible to top the Carnot cycle efficiency. Here, the authors show that in a...
